[jira] [Comment Edited] (OOZIE-3105) testJMXInstrumentation from the org.apache.oozie.util.TestMetricsInstrumentation class is flaky

    [ https://issues.apache.org/jira/browse/OOZIE-3105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16227373#comment-16227373 ]

[~dbist13] thanks for taking care of this. Recently I've been thinking about creating an umbrella JIRA that includes all flaky tests we have right now, I wanted to include this as well. But I don't fully understand this patch, how does using {{assumeNotNull}} instead of {{assertNotNull}} eliminate the flakyness? It just makes JUnit skip the test, no?
