opt is our config where we do not set fastdebug or slowdebug. In the configure log of it it shows : * Debug level: release * HS debug level: product

I did run fastdebug build only. Actually that's a default-vm-mode on my system. Update: By "opt.", you mean "release-vm" right ? Or is it actually the optimized-vm-build you're talking about.

> Is there any obvious difference between s390x/ppc error reporting. Looks like ppc took different codepath to report the failure. Not sure about that. The only thing I can say, we see the guarantee when testing with the fastdebug binaries, not with opt. Maybe you did not run (fast)debug ?

Thanks for pointing it out :), i will update it for s390 and ppc. My guess is as change is not done for ppc so it fails there as well.

The bug is here: https://github.com/openjdk/jdk/blob/eb0d1ce9487df000b4675901cc0d18f6a1c86348/test/hotspot/jtreg/runtime/ErrorHandling/ShowRegistersOnAssertTest.java#L73 "null" needs to be replaced for all platforms. The code currently only works for x86 and aarch64.

[~mbaesken] did you saw this on SAP daily builds? I am not sure how if it is related to s390x or I could be unlucky.

The test runtime/ErrorHandling/ShowRegistersOnAssertTest.java fails as well on Linux ppc64le, we run into this assertion (fastdebug build) : # Internal Error (/priv/jenkins/client-home/workspace/openjdk-jdk-linux_ppc64le-dbg/jdk/src/hotspot/share/utilities/vmError.cpp:2137), pid=20343, tid=20344 # guarantee(how == 0) failed: test guarantee # native stack : Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [libjvm.so+0x1d5a68c] VMError::report_and_die(int, char const*, char const*, char*, Thread*, unsigned char*, void const*, void const*, char const*, int, unsigned long)+0x3fc (vmError.cpp:2137) V [libjvm.so+0xb21d78] report_vm_error(char const*, int, char const*, char const*, ...)+0xd8 (debug.cpp:196) V [libjvm.so+0x1d53bb8] VMError::controlled_crash(int)+0x188 (vmError.cpp:2137) V [libjvm.so+0x11a0178] JNI_CreateJavaVM+0x4b8 (jni.cpp:3630) C [libjli.so+0x66a0] JavaMain+0xd0 (java.c:1488) C [libjli.so+0xb6e8] ThreadJavaMain+0x18 (java_md.c:633) C [libc.so.6+0xb0044] start_thread+0x184
