6908208: UseCompressedOops: array_size() returns incorrect size for MAX_INT object array following 6906727 Summary: In array_size() cast to an unsigned to avoid overflow of intermediate value. Reviewed-by: kvn, tonyp, jmasa, jcoomes, coleenp

6904967: G1: some CollectionUsageThreshold tests fail Summary: ensure that max and committed are non-zero (currently: at least as large as the region size). Reviewed-by: iveresov, mchung

6906727: UseCompressedOops: some card-marking fixes related to object arrays Summary: Introduced a new write_ref_array(HeapWords* start, size_t count) method that does the requisite MemRegion range calculation so (some of the) clients of the erstwhile write_ref_array(MemRegion mr) do not need to worry. This removed all external uses of array_size(), which was also simplified and made private. Asserts were added to catch other possible issues. Further, less essential, fixes stemming from this investigation are deferred to CR 6904516 (to follow shortly in hs17). Reviewed-by: kvn, coleenp, jmasa

6899058: G1: Internal error in ptrQueue.cpp:201 in nightly tests Summary: Fixes a race on the dirty card queue completed buffer list between worker thread(s) performing a flush of a deferred store barrier (enqueueing a newly completed buffer) and worker thread(s) in the RSet updating code claiming completed buffers. Removed the routine that removes elements from the completed update buffer queue using a CAS. Reviewed-by: ysr, tonyp

6902303: G1: ScavengeALot should cause an incremental, rather than a full, collection Summary: ScavengeALot now causes an incremental (but possibly partially young, in the G1 sense) collection. Some such collections may be abandoned on account of MMU specs. Band-aided a native leak associated with abandoned pauses, as well as an MMU tracker overflow related to frequent scavenge events in the face of a large MMU denominator interval; the latter is protected by a product flag that defaults to false.

6898948: G1: forensic instrumentation for out-of-bounds recent_avg_pause_time_ratio() Summary: Added instrumentation and (temporary) assert in non-product mode; clipped the value when found out-of-bounds in product mode.
