I am able to reproduce that java just crashes.

Under full system emulation, it even crashes in a different way

ace=1018k
v=VM code, C=native code)
C  [linux-vdso64.so.1+0x6f4]  __kernel_getcpu+0x4
V  [libjvm.so+0xa7ccae]  os::init_2()+0x23e

C  [libjli.so+0x4e8c]  JavaMain+0xbc
C  [libjli.so+0xa370]  ThreadJavaMain+0x20


Because we don't support access register mode yet ...

Long story short, it might take a while until we can run java under QEMU 
s390x with TCG.
