Ah, according to the bug report, this particular issue affects older SPARC CPUs only. This explains why it happens on the UltraSPARC T1 but currently not on the SPARC T5.

Will keep on digging! Thanks for the additional pointers.

Ok, so the actual crash after working around JDK-8144448 now seems this one:
