    Abstract Classes vs. Interfaces, Performance Benchmarking, JMH, Lambdas and Databases--127th airhacks.tv airhacks.tv with the following topics:
    "String.join() is 30% faster than Collectors.joining(), JMH not always necessary for high-level benchmarking, interfaces slightly faster than abstract classes but the difference is negligible, Quarkus requires no installation - just use the POM file, Quarkus tests are integration tests and should be used sparingly, use shutdown hooks or @PreDestroy for clean connection closure in Lambdas, GraalVM shines in CLI tools and polyglot applications, simple export method for Java version management, JavaFX on mobile is challenging but viable with Gluon, EJBs and some Java EE concepts are outdated, but interceptors and dependency injection are still relevant"

    3. performance measurement with or without JMH: "PLEASE use the microbenchmark harness in future videos. I have the impression, that this suggests that performance measurements with after-minus-before is a good idea." from: What is Faster: String.join or Collectors.joining?

    Live from JCON Europe 2024: "Serverless Java #slideless" JCON Europe 2024.

    I used the following template in this talk as base for the examples: aws-functionurl-cdk-only. However, most of my real-world projects rely on the: aws-quarkus-lambda-cdk-plain project.

    See you at airhacks.live!.

    The abstract:

    Serverless is the least complex, most secure, cost-effective (or even free) architecture for most enterprise applications and is compatible with the "Green IT" premises. In this session, I will explain the inner workings of a serverless application from a code perspective with IaC provisioning with Java, real-world MicroProfile code, and live deployments. I will answer your questions in real-time.

What is the difference between a function and a microservice? Are synchronous functions an anti-pattern? How to efficiently structure Java applications' business and IaC code. I will discuss "working" practices and patterns with code and live deployments in this code-focused session. Attendees' questions are highly appreciated!"

    ...as always the abstract was just a suggestion and I also enjoyed the questions and discussions before (we had a short pre-show :-)), during and after the talk.

    The talk was recorded and is available on:

    From Jakarta EE ManagedExecutorService to MicroProfile ManagedExecutor ManagedExecutorService instance is injectable via the @Resource annotation:
    
    import javax.enterprise.concurrent.ManagedExecutorService;
    public class EventSource {
    
        
        @Resource
        ManagedExecutorService threadPool;

    }
    
    
    [code from: Java EE 8: Sending asynchronous CDI 2.0 events with ManagedExecutorService]

    In pure MicroProfile environments these API is not available but can be replaced with ManagedExecutor from MicroProfile Context Propagation:

    
    import org.eclipse.microprofile.context.ManagedExecutor;
    public class EventSource {
    
        @Inject
        ManagedExecutor executor;
    }
    
    

    Both injected instances are inheriting from ExecutorService. Migration from javax.enterprise.concurrent.ManagedExecutorService to org.eclipse.microprofile.context.ManagedExecutor should be matter of replacing @Resource with @Inject, renaming the injected classes and fixing the imports.

    3. I'm moving from Payara to Quarkus but I can't make sense of the CXF plugin for Quarkus(...)
    4. Would you include a dependency to your project even if you only need a small portion of functionality or dev/copy this single function on your own?
    5. Java Releases now seem to have the tend to add more and more syntax sugars to the language (modules, var, records,…). Whats your opinion on that? Will it help the language to grow or does it make it more unaccessible for inexperienced developers?
    6. Recent Java additions (Off-Heap-Memory, SIMD) seem to offer a memory mgmt. outside of the GC or a vendor specific instruction set. Given those new possibilities in Java do you think it will introduce new complexity for JDK/GC developers to introduce improvements since those features are outside the range of a managed environment?

    JCon 2022 Conference Keynote: Thinking About Persistence for Serverless Java Thanks for all the questions and interactions. This keynote was fun!

    Abstract:

    "Serverless Java applications are stateless and store their data in a range of cloud persistence stores, from relational databases, like Aurora, over file-based block storage like S3 to persistent event stores like Kinesis.

    In this keynote, I will focus on the characteristics and challenges of serverless Lambda and Fargate Java application's data access layer and discuss the impact on authentication, authorization, connection handling or scalability, data mapping, portability, and costs. Your questions are highly welcome!"

    Closing JAX-RS Response with try-with-resources Response implements AutoCloseable. It can either be closed explicitly, or via try-with-resources:
    
    import static org.junit.jupiter.api.Assertions.assertNotNull;
    import javax.inject.Inject;
    import org.eclipse.microprofile.rest.client.inject.RestClient;
    import org.junit.jupiter.api.Test;
    import io.quarkus.test.junit.QuarkusTest;
    
    @QuarkusTest
    public class AutocloseableResponseIT {
    
        @Inject
        @RestClient
        WebsiteClient client;
    
        @Test
        void closeExplicitly(){
            var response = this.client.getContent();
            var content = response.readEntity(String.class);
            response.close();
            assertNotNull(content);
        }
    
        @Test
        void autoClose(){
            try(var response = this.client.getContent()){

                assertNotNull(content);
            }
        }
    }
    
    

    The corresponding client (Rest Client for MicroProfile) used in this example is:

    
    import javax.ws.rs.GET;
    import javax.ws.rs.Produces;
    import javax.ws.rs.core.MediaType;
    import javax.ws.rs.core.Response;

    @RegisterRestClient(baseUri = "http://localhost:8080")
    public interface WebsiteClient {
        
        @GET
        @Produces(MediaType.TEXT_PLAIN)
        Response getContent();
    }
    
    

    Too many "open" Responses may lead to blocking behavior.

    Quarkus, Hanging MP REST Client and the Solution (Rest Client for MicroProfile) interface:
    
    @RegisterRestClient(baseUri = "http://localhost:8000")
    public interface WebsiteClient {
        
        @GET
        @Produces(MediaType.TEXT_PLAIN)
        Response getContent();
    }
    
    

    ...injected to Quarkus JAX-RS resource:

    
    
    import javax.inject.Inject;
    import javax.ws.rs.GET;
    import javax.ws.rs.Path;
    import javax.ws.rs.core.Response;
    
    import org.eclipse.microprofile.rest.client.inject.RestClient;
    
    @Path("website")
    public class WebsiteResource {
    
    
        @Inject
        @RestClient
        WebsiteClient firstClient;
    
        @Inject
        @RestClient
        WebsiteClient secondClient;
    
        @GET
        public String injected() {
            for (int i = 0; i < 500; i++) {
                Response firstResponse = this.firstClient.getContent();
                Response secondResponse = this.secondClient.getContent();
                System.out.println(i);
            }
            return "+";
        }    
    }
    
    

    will block after 50 iterations.

    Reason: the exhaustion of the underlying HTTP connection pool. See stack trace:

    
    org.apache.http.pool.AbstractConnPool.getPoolEntryBlocking(AbstractConnPool.java:393)
    org.apache.http.pool.AbstractConnPool.access$300(AbstractConnPool.java:70)
    org.apache.http.pool.AbstractConnPool$2.get(AbstractConnPool.java:253)
    org.apache.http.pool.AbstractConnPool$2.get(AbstractConnPool.java:198)
    org.apache.http.impl.conn.PoolingHttpClientConnectionManager.leaseConnection(PoolingHttpClientConnectionManager.java:306)
    org.apache.http.impl.conn.PoolingHttpClientConnectionManager$1.get(PoolingHttpClientConnectionManager.java:282)
    org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:190)
    org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:186)
    org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:89)
    org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:110)
    org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:185)
    org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:83)
    org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:56)
    org.jboss.resteasy.client.jaxrs.engines.ManualClosingApacheHttpClient43Engine.invoke(ManualClosingApacheHttpClient43Engine.java:302)
    
    

    The underlying resources are freed with the Response#close call, now all 500 iterations are performed without blocking:

    
    @GET
    public String injected() {
        for (int i = 0; i < 500; i++) {
            Response firstResponse = this.firstClient.getContent();
            firstResponse.close();
            Response secondResponse = this.secondClient.getContent();
            firstResponse.close();
            System.out.println(i);
        }
        return "+";
    }    
    
    

    The blocking behaviour depends on the JAX-RS / MicroProfile Rest Client implementation. RESTEasy requires an explicit Response#close call, Jersey does not.

    Time Measurement with Duration, Instant, and ISO-8601 Duration is a viable alternative to System.currentTimeMillis() for time measurements (also checkout: Beyond System.currentTimeMillis: Measuring Time with Duration and Instant):
    
    import java.time.Duration;
    import java.time.Instant;
    import java.util.concurrent.TimeUnit;
    import org.junit.jupiter.api.Test;
    
    public class DurationToStringTest {
    
        void slow(){
            try {
                TimeUnit.SECONDS.sleep(1);
            } catch (InterruptedException e) {}
        }
    
        @Test
        public void durationToString() throws InterruptedException {
            var start = Instant.now();
            this.slow();
            var duration = Duration.between(start, Instant.now());
            var durationAsString = duration.toString();  //ISO-8601
            System.out.println(durationAsString);
        }
    }
    
    

    The method Duration#toString returns a combined representation of hours, minutes, seconds and fractional seconds, standardized by ISO-8601.

    The above example produces the following output: PT1.001087S.

    From Java Object to JSON-P Type with "Pattern Matching for instanceof" JEP 305: Pattern Matching for instanceof allows a more concise type conversion; the method javaToJson tests the type of the Java object and converts it to the corresponding JSON-P without casting:

    
    import org.junit.jupiter.api.Test;
    import static org.junit.jupiter.api.Assertions.assertEquals;
    
    import java.util.List;
    import jakarta.json.Json;
    import jakarta.json.JsonValue;
    import jakarta.json.JsonValue.ValueType;
    
    public class PatternMatchingTest {
    
        JsonValue javaToJson(Object javaType){
            if (javaType instanceof String string) {
                return Json.createValue(string);
            } else if (javaType instanceof Integer integer) {
                return Json.createValue(integer);
            } else if (javaType instanceof Boolean bool) {
                return bool? JsonValue.TRUE : JsonValue.FALSE;
            }
            return Json.createValue(javaType.toString());
        }
    
    }   
    
    

    Now a List of various Java types can be converted to the corresponding JSON-P (Jakarta JSON Processing) values:

    
    @Test
    public void instanceOfWithoutCasting() {
        var mix = List.of("duke",42,true);
    
        assertEquals(ValueType.STRING, javaToJson(mix.get(0)).getValueType());
        assertEquals(ValueType.NUMBER, javaToJson(mix.get(1)).getValueType());
        assertEquals(ValueType.TRUE, javaToJson(mix.get(2)).getValueType());
    }

    Duration Conversion with java.util.concurrent.TimeUnit java.util.concurrent.TimeUnit provides methods to convert across various time units.

    As an example, the following test converts three seconds to milliseconds:

    
    @Test
    public void secondsToMs() {
        var expected = 3 * 1000;
        var actual = TimeUnit.SECONDS.toMillis(3);
        assertEquals(expected, actual);
    }
    
    

    Now from milliseconds to minutes:

    
    @Test
    public void msToMinutes() {
        var expected = 3;
        var actual = TimeUnit.MILLISECONDS.toMinutes(180000);
        assertEquals(expected, actual);
    }
    
    

    With TimeUnit we can even wait for the next vacations:

    
    @Test
    public void sleepWithTimeUnitForThreeSeconds() throws InterruptedException {
        long start = System.currentTimeMillis();
        
        TimeUnit.SECONDS.sleep(3);
        //TimeUnit.DAYS.sleep(300); :-)
    
        var duration = System.currentTimeMillis() - start;
        assertTrue(duration >= 3000);
    }

    More Convenience with Rest Client for MicroProfile and Method Overloading JAX-RS resource with optional header, or query parameters:
    
    import javax.ws.rs.DefaultValue;
    import javax.ws.rs.GET;
    import javax.ws.rs.HeaderParam;
    import javax.ws.rs.Path;
    import javax.ws.rs.Produces;
    import javax.ws.rs.core.MediaType;
    
    @Path("/hello")
    public class GreetingResource {
    
        @GET
        @Produces(MediaType.TEXT_PLAIN)
        public String hello(@DefaultValue("james") @HeaderParam("firstName") String firstName,
                            @DefaultValue("duke") @HeaderParam("lastName") String lastName) {
            return firstName + " " + lastName;
        }
    }
    
    

    ...is accessible via a Rest Client for MicroProfile interface with overloaded methods:

    
    import javax.ws.rs.GET;
    import javax.ws.rs.HeaderParam;
    import javax.ws.rs.Path;
    import javax.ws.rs.Produces;
    import javax.ws.rs.core.MediaType;
    
    import org.eclipse.microprofile.rest.client.inject.RegisterRestClient;
    
    @Path("/hello")
    @Produces(MediaType.TEXT_PLAIN)
    @RegisterRestClient(baseUri = "http://localhost:8080")
    public interface GreetingResourceClient {
    
        @GET
        public String hello(@HeaderParam("firstName") String firstName, @HeaderParam("lastName") String lastName);
    
        @GET
        public String hello(@HeaderParam("firstName") String firstName);
    
        @GET
        public String hello();
        
    }
    
    

    Now the client can be injected and the overloaded methods conveniently called:

    
    import static org.junit.jupiter.api.Assertions.assertEquals;
    
    import javax.inject.Inject;
    
    import org.eclipse.microprofile.rest.client.inject.RestClient;
    import org.junit.jupiter.api.Test;
    
    import io.quarkus.test.junit.QuarkusTest;
    
    @QuarkusTest
    public class GreetingResourceTest {
    
        @Inject
        @RestClient
        GreetingResourceClient client;
    
        @Test
        void helloWithoutParameters(){
            var hello = this.client.hello();
            assertEquals(hello, "james duke");
        }
    
        @Test
        void helloWithFirstName(){
            var hello = this.client.hello("john");
            assertEquals(hello, "john duke");
        }
    
        @Test
        void helloWithFirstNameAndLastName(){
            var hello = this.client.hello("john","dukem");
            assertEquals(hello, "john dukem");
        }  
    }

        @Test
        public void emptyList() {
            var emptyList = Collections.<String>emptyList();
