  1. jshell (JEP 222) -- the REPL for Java 9 is GA and is going to be available in the binary builds in the next days / weeks.
  2. jshell comes with a thin API which can be used to execute Java code on-the-fly.
  3. Jersey 3.0 will implement JAX-RS 2.1 API, non-blocking IO, reactive JAX-RS 2.0 client, server-sent events and will integrate with Weld SE out-of-the box.
  4. The custom JavaOne t-shirt factory didn't scale at all. The queue was synchronized with only two lazy worker threads competing for a scarce resource. No timeouts, no Cirquit Breaker.
  5. My Nashorn session attended the vast majority of the Nashorn engineering team at Oracle. Knowing that, I offered the attendees to ask me even low level JavaScript / byte code questions. My secret plan was to act as a facade :-). I explained distributed lambdas with headlands, flexible data transformations with enhydrator, static page generation with spg and automation scripts to install / configure Payara or monitor docker.
  6. I didn't attended the appreciation event and used the time for compaction and garbage collection of Stream.of(javaone.information()).
