Comments
These two stub are just checked if they are generated or not by PrintClasses.java test case, but never executed. Execution happens with these two testcase: test/jdk/jdk/jfr/threading/TestManyVirtualThreads.java jdk/jfr/threading/TestStringPoolVirtualThreadPinning.java

Test is failing because of nullptr returned by these two method in sharedRuntime_s390 file: #if INCLUDE_JFR RuntimeStub* SharedRuntime::generate_jfr_write_checkpoint() { if (!Continuations::enabled()) return nullptr; Unimplemented(); return nullptr; } RuntimeStub* SharedRuntime::generate_jfr_return_lease() { if (!Continuations::enabled()) return nullptr; Unimplemented(); return nullptr; } #endif // INCLUDE_JFR
