I just gave this a quick run through testing and I'm seeing the following error with an internal test:


# A fatal error has been detected by the Java Runtime Environment:
#
#  Internal Error (.../open/src/hotspot/share/opto/escape.cpp:1112), pid=31841, tid=41475
#  fatal error: EA unexpected CallLeaf SharedRuntime::trace_id_load_barrier
