The error message I see in the logs is

GC triggered before VM initialization completed. Try increasing NewSize, current value 1280K.

Do you know why the NewSize is so small?  I ask because I'm
not sure setting a larger heap size will always fix this failure.

If the test is run (with the parameters that fail) and -Xlog:gc*=trace, 
you might
see why the NewSize is so small (if you don't know now).
