50x internal grinder - failed 6/50

[hzongaro]

@BradleyWood, may I ask you to look at this failure? I was able to reproduce the failure in an internal grinder run with the option -Xdump:jit+system:events=throw+systhrow,filter=java/lang/NullPointerException#java/lang/Class.copyFields. Hopefully the core and jitdump files there were produced will help you to get started.
