Feedback on new JDK 9 features

Make G1 the Default Garbage Collector

As described in JEP 248, switching to a low-pause collector in JDK 9 such as G1 should provide a better overall experience, for most users, than a throughput-oriented collector such as the Parallel GC, which is currently the default. A call for feedback and data points regarding this change went out on the hotspot-dev mailing list, where such input should be provided.

jshell: The Java Shell (Read-Eval-Print Loop)

As described in JEP 222, Project Kulla introduces a new REPL for JDK 9.  You can test it by following the instructions from the latest Adoption Group hackday. Feedback on this feature should be provided on the kulla-dev mailing list.

OpenJDK JarSigner API

JDK 9 is more restricted on calling sun.* public methods but we know there are users calling sun.security.tools.jarsigner.Main to sign jar files. A new API is proposed for this very purpose in OpenJDK. Feedback on this API should be provided on the security-dev mailing list.
