Description
G1 asserts with the following error when deferred RS update is disabled. # after -XX: or in .hotspotrc: SuppressErrorAt=/g1GCPhaseTimes.cpp:155 ============================================================================== Unexpected Error ------------------------------------------------------------------------------ Internal Error at g1GCPhaseTimes.cpp:155, pid=3097, tid=140579531847424 assert(_data[i] != _uninitialized) failed: Invalid data for worker 0, data: -1.000000, uninitialized: -1.000000 Do you want to debug the problem? To debug, run 'gdb /proc/3097/exe 3097'; then switch to thread 140579531847424 (0x00007fdb390ef700) Enter 'yes' to launch gdb automatically (PATH must include gdb) Otherwise, press RETURN to abort... ============================================================================== P5 because G1DeferredRSUpdate is debug only, and needs to be explicitly set.
