      8015660: Test8009761.java "Failed: init recursive calls: 24. After deopt 25" · 69b09c77
      由 minqi 提交于 
      Summary: Windows reserves and only partially commits thread stack. For detecting more thread stack space for execution,  Windows installs one-shot page as guard page just before the current commited edge. It will trigger STACK_OVERFLOW_EXCEPTION when lands on last 4 pages of thread stack space. StackYellowPages default value is 2 on Windows (plus 1 page of StackRedPages, 3 pages guarded by hotspot) so the exception happens one page before Yellow pages. Same route executed second time will have one more page brought in, this leads same execution with different stack depth(interpreter mode). We need match Windows settings so the stack overflow exception will not happen before Yellow pages.

      6976350: G1: deal with fragmentation while copying objects during GC · fc475a94
      由 tamao 提交于 
      Summary: Create G1ParGCAllocBufferContainer to contain two buffers instead of previously using one buffer, in order to hold the first priority buffer longer. Thus, when some large objects hits the value of free space left in the first priority buffer it has an alternative to fit in the second priority buffer while the first priority buffer is given more chances to try allocating smaller objects. Overall, it will improve heap space efficiency.
