Added a requires to force SerialGC The following occurs when running DeoptimizeRelocatedNMethod on PPC64 # Internal Error (jdk/src/hotspot/cpu/ppc/nativeInst_ppc.cpp:405) # assert(!decode(i1, i2)) failed: already patched Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [libjvm.so+0x1701784] NativePostCallNop::patch(int, int)+0xf4 (nativeInst_ppc.cpp:405) V [libjvm.so+0x1718414] nmethod::finalize_relocations()+0x6f4 (nmethod.cpp:2059) V [libjvm.so+0x171891c] nmethod::post_init()+0x5c (nmethod.cpp:1252) V [libjvm.so+0x171a8dc] nmethod::relocate(CodeBlobType)+0x1ec (nmethod.cpp:1515) V [libjvm.so+0x200b598] WB_RelocateNMethodFromMethod+0x388 (whitebox.cpp:1653) j jdk.test.whitebox.WhiteBox.relocateNMethodFromMethod0(Ljava/lang/reflect/Executable;I)V+0 j jdk.test.whitebox.WhiteBox.relocateNMethodFromMethod(Ljava/lang/reflect/Executable;I)V+8 j compiler.whitebox.DeoptimizeRelocatedNMethod.main([Ljava/lang/String;)V+50 @TheRealMDoerr @reinrich Do you have any ideas on a solution for this? I don't have any experience working with PPC so guidance would be greatly appreciated ------------- PR Comment: https://git.openjdk.org/jdk/pull/27659#issuecomment-3403992989
