7098282: G1: assert(interval >= 0) failed: Sanity check, referencePolicy.cpp: 76 Summary: There is a race between one thread successfully forwarding and copying the klass mirror for the SoftReference class (including the static master clock) and another thread attempting to use the master clock while attempting to discover a soft reference object. Maintain a shadow copy of the soft reference master clock and use the shadow during reference discovery and reference processing. Reviewed-by: tonyp, brutisso, ysr

7099454: /bin/sh does not support syntax used in the src/os/posix/launcher/launcher.script shell script Summary: Also reviewed by mikael.gerdin@oracle.com; Changed to the `` syntax instead. Also changed "source" to ".". Reviewed-by: never, stefank, dsamersoff, rottenha

7095236: G1: _markedRegions never contains NULL regions Summary: Removed the code for skipping over NULL regions in _markedRegions, replacing it with an assertion that a NULL region is never encountered; removed dead methods, remove() and remove_region(), and inlined a simplified addRegion() directly into fillCache(). Reviewed-by: brutisso, tonyp

7005808: G1: re-enable ReduceInitialCardMarks for G1 Summary: Remove the extra guard to allow G1 to use ReduceInitialCardMarks Reviewed-by: jmasa, tonyp, johnc, ysr

7095194: G1: HeapRegion::GrainBytes, GrainWords, and CardsPerRegion should be size_t Summary: Declare GrainBytes, GrainWords, and CardsPerRegion as size_t. Reviewed-by: jcoomes, tonyp, jmasa

7021322: assert(object_end <= top()) failed: Object crosses promotion LAB boundary Summary: Pass the same object size value to both allocate and unallocate_object Reviewed-by: ysr, brutisso

7097048: G1: extend the G1 SA changes to print per-heap space information Reviewed-by: brutisso, johnc

7097053: G1: assert(da ? referent->is_oop() : referent->is_oop_or_null()) failed: referenceProcessor.cpp:1054 Summary: During remembered set scanning, the reference processor could discover a reference object whose referent was in the process of being copied and so may not be completely initialized. Do not perform reference discovery during remembered set scanning. Reviewed-by: tonyp, ysr

7086533: G1: assert(!_g1->is_obj_dead(obj)): We should not be preserving dead objs: g1CollectedHeap.cpp:3835 Summary: Some objects may not be marked in the event of an evacuation failure in a partially young GC, during a marking cycle. Avoid this situation by not allowing partially young GCs during a marking cycle. Reviewed-by: tonyp, ysr, brutisso

7091366: re-enable quicksort tests Summary: Added extern "C" to make it build with JDK6 compilers Reviewed-by: jwilhelm, kvn

7075646: G1: fix inconsistencies in the monitoring data Summary: Fixed a few inconsistencies in the monitoring data, in particular when reported from jstat. Reviewed-by: jmasa, brutisso, johnc

6484982: G1: process references during evacuation pauses Summary: G1 now uses two reference processors - one is used by concurrent marking and the other is used by STW GCs (both full and incremental evacuation pauses). In an evacuation pause, the reference processor is embedded into the closures used to scan objects. Doing so causes causes reference objects to be 'discovered' by the reference processor. At the end of the evacuation pause, these discovered reference objects are processed - preserving (and copying) referent objects (and their reachable graphs) as appropriate.

7092245: G1: Wrong format specifier in G1PrintRegionLivenessInfo header output Summary: Cast HeapRegion::GrainBytes to size_t in output statement. Reviewed-by: ysr, brutisso, pbk, tonyp

7091032: G1: assert failure when NewRatio is used Summary: The desired min / max heap sizes are miscalculated at initialization when NewRatio is used. The changeset also includes an additional small change to turn a print statement into a warning. Reviewed-by: johnc, jmasa, ysr, brutisso

7068215: G1: Print reference processing time during remark Summary: Displays the elapsed time taken to perform reference processing during remark as part of the PrintGCDetails output. Reviewed-by: ysr

7045232: G1: pool names are inconsistent with other collectors (don't have 'Space') Summary: Make sure the eden and survivor pools have "Space" in their name. Reviewed-by: jmasa, ysr

7092412: G1: Some roots not marked during an initial mark that gets an evacuation failure Summary: As a result of the changes for 7080389, an evacuation failure during an initial mark pause may result in some root objects not being marked. Pass whether the caller is a root scanning closure into the evacuation failure handling code so that the thread that successfully forwards an object to itself also marks the object. Reviewed-by: ysr, brutisso, tonyp

7059019: G1: add G1 support to the SA Summary: Extend the SA to recognize the G1CollectedHeap and implement any code that's needed by our serviceability tools (jmap, jinfo, jstack, etc.) that depend on the SA. Reviewed-by: never, poonam, johnc
