rev 4279 : 8009940: G1: assert(_finger == _heap_end) failed, concurrentMark.cpp:809
Summary: Skip reference processing if the global marking stack overflows during remark. Do not call set_phase() from within parallel reference processing; use reset_for_reuse() instead. CMTask-0 should reset the marking state only during the concurrent phase of the marking cycle; if an overflow occurs at any stage during the remark, the marking state will be reset after reference processing.
