pmap and pstack are not even supported on OSX with a live process. The
automated github testing did not catch this because it passed due to the above
check:
TEST RESULT: Passed. Skipped: jtreg.SkippedException: Cannot run this test on
OSX if adding privileges is required.
If it passed the check, it would have failed below to find a .dylib. You could
change the code below to something like what is in ClhsdbPmap.java:
if (!withCore && Platform.isOSX()) {
expStrMap.put("pmap", List.of("Not available for Mac OS X
processes"));
} else {
expStrMap.put("pmap", List.of("jvm", "java", "jli", "jimage"));
}
