Subject [jira] [Created] (HADOOP-14851) LambdaTestUtils.eventually() doesn't spin on Assertion failures
Date Fri, 08 Sep 2017 11:20:00 GMT
Steve Loughran created HADOOP-14851:

             Summary: LambdaTestUtils.eventually() doesn't spin on Assertion failures
                 Key: HADOOP-14851
                 URL: https://issues.apache.org/jira/browse/HADOOP-14851
             Project: Hadoop Common
          Issue Type: Bug
          Components: test
    Affects Versions: 2.8.1
            Reporter: Steve Loughran
            Assignee: Steve Loughran

This is funny. The {{LsmbdaTestUtils.eventually()}} method, meant to spin until a closure
stops raising exceptions, doesn't catch {{Error}} and subclasses, so doesn't fail on an {{Assert.assert()}}
failure, which raises an {{AssertionError}}. My bad :)

        () -> {
          while (counter.incrementAndGet()  < 5) {
            assert false : "oops";

Fix: catch Throwable, rethrow. Needs to add VirtualMachineError & subclasses to the set
of errors not to spin on (OOM, stack overflow, ...)
