8040655: When processing a RewriteException debug object, the return value has already been reset to null. We need to catch this value before that. Reviewed-by: attila, lagergren Contributed-by: matherey.nunez@oracle.com

8040102: Remove all references to Unsafe and definition of anonymous clases from the code Summary: As the catch combinator optimization is now part of java.lang.invoke we don't need to put our own in the boot class path in any configuration anymore. Furthermore, with the completion of the array performance subtask of optimistic typing, we can remove the experimental (commented out) Unsafe accessors in the ArrayData classes Reviewed-by: attila, jlaskey

8027043: Turn global accesses into MethodHandle.constant, with one chance of reassignment, e.g. x = value occuring once in the global scope is ok, twice is not. Reviewed-by: attila, sundar, jlaskey

8038416: Access to undefined scoped variables deoptimized too much Reviewed-by: jlaskey, lagergren

8038406: Testability: as a first step of moving loggers away from the process global space, the Debug object now supports logging POJOs from log entries as an event queue, which can be introspected from test scripts. This is way better than screen scraping brittle and subject-to-change log output. Reviewed-by: attila, hannesw, sundar
