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=/assemblersparc.cpp:52 # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (/srv/openjdk/hs/src/hotspot/cpu/sparc/assemblersparc.cpp:52), pid=18610, tid=18620 # assert(!(iscti(prev) && iscti(insn))) failed: CTI-CTI not allowed. # # JRE version: OpenJDK Runtime Environment (11.0) (fastdebug build 11-internal+0-adhoc.glaubitz.hs) # Java VM: OpenJDK 64-Bit Server VM (fastdebug 11-internal+0-adhoc.glaubitz.hs, mixed mode, tiered, compressed oops, serial gc, linux-sparc) # No core dump will be written.

Can you provide the stacktrace for the above please.
