John Cuthbertson	79c90a15fa	7143511: G1: Another instance of high GC Worker Other time (50ms) ... Tiered compilation has increased the number of nmethods in the code cache. This has, in turn, significantly increased the number of marked nmethods processed during the StrongRootsScope destructor. Create a specialized version of CodeBlobToOopClosure for G1 which places only those nmethods that contain pointers into the collection set on to the marked nmethods list.

Antonios Printezis	450d6e8d9a	7146246: G1: expose some of the -XX flags that drive which old regions to collect during mixed GCs ... Make two G1 cmd line flags available in product builds: G1HeapWastePercent (previously called: G1OldReclaimableThresholdPercent) and G1MixedGCCountTarget (previous called: G1MaxMixedGCNum). Also changed the default of the former from 1% to 5% and the default for G1OldCSetRegionLiveThresholdPercent to 90%. Reviewed-by: azeemj, jwilhelm, johnc	2012-03-23 10:53:19 -04:00
John Cuthbertson	006def0451	7147724: G1: hang in SurrogateLockerThread::manipulatePLL ... Attempting to initiate a marking cycle when allocating a humongous object can, if a marking cycle is successfully initiated by another thread, result in the allocating thread spinning until the marking cycle is complete. Eliminate a deadlock between the main ConcurrentMarkThread, the SurrogateLocker thread, the VM thread, and a mutator thread waiting on the SecondaryFreeList_lock (while free regions are going to become available) by not manipulating the pending list lock during the prologue and epilogue of the cleanup pause.
