Unfortunately, we know both java/openjdk6 and java/openjdk7 are
unusable for some environment.  Basically, C2 (server JIT compliler)
crashes with SIGSEGV/SIGBUS at random addresses.  It is not clear why
it only happens on certain platforms, however.

It is known that disabling background compilation helps, i. e.,
"-Xbatch".  For i386 case, you can also use C1 (client JIT compiler),
i. e., "-client"
