Try adding --px-default=allregs-at-mem-access.  If that doesn't help
then try --px-default=allregs-at-each-insn.  You'll take a big performance
hit though.

It might also be -- looking at the other info in the report -- that this is
some kind of security sandbox problem, in which the process is denied
permission to proceed further at some point, because it is Valgrind that
is running, not the JVM.  In which case the above flags won't help.
