Kim Barrett	8bfa163a68	8132306: java/lang/ref/ReferenceEnqueue.java fails with "RuntimeException: Error: poll() returned null; expected ref object" ... Carefully order ref.queue and queue list updates to address races. Reviewed-by: dholmes, dfuchs, plevart	2015-08-04 17:26:14 -04:00
Y. Srinivas Ramakrishna	e9207384c5	4243978: (ref) Race condition in Reference.enqueue() ... 4268317: (ref) Reference.isEnqueued() can return true when instance not enqueued The reference handler now declares, and assumes, that the discovered field, rather than the next field, is (to be) used to link the entries in the pending list, thus allowing a reference object to be safely enqueued even while it is in the pending state. Also added slightly modified regression tests from the two bug reports. Reviewed-by: mchung, alanb, jcoomes	2011-10-31 17:38:15 -07:00
