Hi,

I randomly scan the qemu-s390x list. If you cc maintainers, or open a

So, all you end up doing is running "/usr/lib/jvm/default-jvm/bin/jar 
--version" inside s390x qemu-user, or is there a real workload that 
triggers the issue?

That might be easy to reproduce. Note that there will most probably be 
other issues when running java workloads. The JVM is known to make use 
of fancy instructions barely used anywhere else (and thus missing in 
qemu-s390x).
