jdk-sandbox: Changelog

6978187: G1: assert(ParallelGCThreads> 1 || n_yielded() == _hrrs->occupied()) strikes again Summary: An evacuation failure while copying the roots caused an object, A, to be forwarded to itself. During the subsequent RSet updating a reference to A was processed causing the reference to be added to the RSet of A's heap region. As a result of adding to the remembered set we ran into the issue described in 6930581 - the sparse table expanded and the RSet scanning code walked the cards in one instance of RHashTable (_cur) while the occupied() counts the cards in the expanded table (_next).

7000578: CMS: assert(SafepointSynchronize::is_at_safepoint()) failed: Else races are possible Summary: Weakened assert in onj_is_alive() to allow its use at initialization time when is_at_safepoint() normally reports false; added some related asserts to check order of is_init_completed() after Universe::is_fully_initialized().

6998802: ScavengeALot: assert(!gch->incremental_collection_failed()) failed: Twice in a row Summary: Weaken assert by excluding scavenges resulting from -XX:+ScavengeALot stress-testing option. Reviewed-by: jmasa, tonyp

6996613: CompactibleFreeListSpace::print should call CompactibleFreeListSpace::print_on, not Space::print_on Reviewed-by: tonyp

6997298: fatal error: must own lock CMS_markBitMap_lock during heap dump Summary: Since we are at a stop-world pause, the existing CMS-phase checks are sufficient for safety, and the locking check can be safely elided. Elaborated documentation comment to the case where class unloading and verification are disabled, and the query happens when we aren't in the sweeping phase, where the answer "false" would be (almost everywhere) too pessimistic.
