jCrete is an unconference organized by Heinz Kabutz (author of the Java Specialist newsletter).
*unconference - top people, informal talks, discussions instead of sessions (most in a restaurant or at the beach).
What I learned:
Unsafe is going to be available in jdk9 with a jre switch on startup. Oracle is working on isolating (boundary checks) the unmanaged heap so that
- mistakes will not mess up the managed heap
- mistakes will not cause a segmentation fault (crash the whole jvm, because someone is trying to read memory from another process)
Oracle might introduce a commercial GC with deterministic stop-the-world pauses.
G1 will become the default GC in jdk9.
I will update this accordingly with more info.
