      7035144: G1: nightly failure: Non-dirty cards in region that should be dirty (failures still exist...)
      Summary: We should only undirty cards after we decide that they are not on a young region, not before. The fix also includes improvements to the verify_dirty_region() method which print out which cards were not found dirty.

      7034139: G1: assert(Thread::current()->is_ConcurrentGC_thread()) failed: only a conc GC thread can call this.
      Summary: We were calling STS join and leave during a STW pause and we are not suppoesed to. I now only call those during  concurrent phase. I also added stress code in the non-product builds to force an overflows (the condition that ws uncovering the bug) to make sure it does not happen again.

      Summary: Created new "new" operator for CHeapObj that allows malloc to fail without causing fatal error. Also replaced "HeapAllocate" with "os::malloc" in decoder code to allow decoder to handle low memory scenario.

      7039089: G1: changeset for 7037276 broke heap verification, and related cleanups · cdee9464
      ysr 提交于
      Summary: In G1 heap verification, we no longer scan perm to G1-collected heap refs as part of process_strong_roots() but rather in a separate explicit oop iteration over the perm gen. This preserves the original perm card-marks. Added a new assertion in younger_refs_iterate() to catch a simple subcase where the user may have forgotten a prior save_marks() call, as happened in the case of G1's attempt to iterate perm to G1 refs when verifying the heap before exit. The assert was deliberately weakened for ParNew+CMS and will be fixed for that combination in a future CR. Also made some (non-G1) cleanups related to code and comments obsoleted by the migration of Symbols to the native heap.

      7011855: G1: non-product flag to artificially grow the heap · dfbf6345
      tonyp 提交于
      Summary: It introduces non-product cmd line parameter G1DummyRegionsPerGC which indicates how many "dummy" regions to allocate at the end of each GC. This allows the G1 heap to grow artificially and makes concurrent marking cycles more frequent irrespective of what the application that is running is doing. The dummy regions will be found totally empty during cleanup so this parameter can also be used to stress the concurrent cleanup operation.
