VMVersion::determinefeatures() needs a code blob, and hence ResourceMark, on sparc and ppc and s390 I think.

But I think the reason that only sparc fails is that VMVersion::determinefeatures() is called too early on Sparc (as part of os::initbeforeergo()). The other platforms call that function later in initialization (VMVersioninit() -> initglobals()). Could that be the error, and if yes, could  VMVersion::determinefeatures()  be delayed?

I just did that but it doesn't really change anything for me.

The main problem is still the assertion failure which I don't really understand is supposed to tell me.

Would be nice if any of the SPARC experts could comment on this:

To suppress the following error report, specify this argument

after -XX: or in .hotspotrc: SuppressErrorAt=/assembler_sparc.cpp:52

A fatal error has been detected by the Java Runtime Environment:

Internal Error (/srv/openjdk/hs/src/hotspot/cpu/sparc/assembler_sparc.cpp:52), pid=18610, tid=18620

assert(!(is_cti(prev) && is_cti(insn))) failed: CTI-CTI not allowed.
