Not available for Mac OS X processes hsdb> + quit The "Not available for Mac OS X processes" message is expected when running on a macosx process, but in this case the test is running the core version of the test, so SA is acting on a core file. The test goes on to fail because there are no threads in the output. The message is generated by PStack.java whenever the thread list is null and it is running on OSX. In that case it assumes the reason the thread list is null is because it is running on a macosx process. It's not clear to me why the thread list is null. I don't see any changes that look like they could cause that. This happens with both x64 and aarch64, although you need to remove the test from the problem list for macosx-aarch64 to get it to reproduce. macosx-x64 is not problem listed. ------------- PR Comment: https://git.openjdk.org/jdk/pull/28284#issuecomment-3545013052
