jdk-sandbox: Changelog

6692906: CMS: parallel concurrent marking may be prone to hanging or stalling mutators for periods of time Summary: Inserted missing yield(check)s in closures used during the work-stealing phase of parallel concurrent marking, a missing synchronous yield-request in the cms perm gen allocation path, and a terminator-terminator for the offer_termination invocation that monitors the yield status of the concurrent marking task. Elaborated some documentation comments and made some task queue termination loop flags configurable at start-up to aid debugging in the field. Reviewed-by: jmasa, johnc, poonam

6423256: GC stacks should use a better data structure 6942771: SEGV in ParScanThreadState::take_from_overflow_stack Reviewed-by: apetrusenko, ysr, pbk

6941395: G1: Use only lock-free versions of region stack push() and pop() Summary: Re-enable use of the lock-free versions of region stack push() and pop() by recording aborted regions in a thread-local structure, which are then processed when scanning of the region stack restarts. The previous locking versions of these routines are retained for diagnostic purposes. Reviewed-by: tonyp, ysr
