One thing to note is that the unhandled exception seems to occur after running the tests. From the output in https://hyc-runtimes-jenkins.swg-devops.com/job/Test_openjdkValhalla_j9_sanity.functional_x86-64_linux_valhalla_Nightly/109/tapResults/:

I ran into this intermittent crash locally. Many thanks to @liqunl. She helped narrow down the crash to "java/lang/AbstractStringBuilder.append(Ljava/lang/CharSequence;)Ljava/lang/AbstractStringBuilder;" Some of her findings below. She might have more to add on the investigation of this issue.

  • Didn't find the difference in the trace logs from this method between the passed case and the failed case
  • This crash doesn't seem to happen after excluding this method and java/lang/StringBuilder.append(Ljava/lang/CharSequence;)Ljava/lang/StringBuilder; which inlines AbstractStringBuilder.append

The internal gc map at the call instruction has the stack map and mark the slot containing the object as live, but the final gc map doesn't have the stack map. Can't tell why we remove the stack map from the trace log, will add some traces to find out.

I could still reproduce this crash with the fix from #10976.

  • Not able to reproduce the crash when limiting the compilation only to the 2 previously suspected methods [1].
  • However it still seems related to AbstractStringBuilder.append based on the backtrace from one of the crashes [2]. I'm trying to reproduce it with trace logs to get more information.
  • The crash is also reproducible after adding disableMergeStackMaps [3].
