tschatzl [Thu, 20 Aug 2015 15:17:43 +0200] rev 32381
8040162: Avoid reallocating PLABs between GC phases in G1 Summary: Allocate G1ParScanThreadState at the start of GC and only deallocate at the end of GC. This automatically keeps the current PLAB intact without flushing it (and loosing lots of memory) for every reallocation. Reviewed-by: david, mgerdin

8003237: G1: Reduce unnecessary (and failing) allocation attempts when handling an evacuation failure Summary: Remember for every generation whether the memory for that generation has already been exhausted. If so, do not try to get a new region for these generations. Further, if the last generation is full, early exit from copy_to_survivor_space. Reviewed-by: jmasa, brutisso
