> This test failure occurs in upstream Jenkins. Looking at the test code, I think it should be improved to capture the root cause of failure:
> E.g. change {{Thread.sleep(1000)}} to {{GenericTestUtils.waitFor}} and use {{GenericTestUtils.assertExceptionContains}} to replace
> {code}
> Assert.assertTrue(ioe.getMessage().contains(info.toString()));
> {code}
