[GitHub] [pulsar] RobertIndie opened a new issue, #15793: Flaky-test: BinaryProtoLookupServiceTest.maxLookupRedirectsTest1

RobertIndie opened a new issue, #15793:
URL: https://github.com/apache/pulsar/issues/15793

   <!--- 
   
   Instructions for reporting a flaky test using this issue template:
   
   1. Replace test_class in title and body with the short test class name WITHOUT the package name.
   2. Replace test_method in title and body with the test method that failed. Multiple methods are flaky, remove the content that refers to the test method.
   3. Replace "url here" with a url to an example failure. In the Github Actions workflow run logs, you can right click on the line number to copy a link to the line. Example of such url is https://github.com/apache/pulsar/pull/8892/checks?check_run_id=1531075794#step:9:377 . The logs are available for a limited amount of time (usually for a few weeks).
   4. Replace "relevant parts of the exception stacktrace here" with the a few lines of the stack trace that shows at least the exception message and the line of test code where the stacktrace occurred.
   5. Replace "full exception stacktrace here" with the full exception stacktrace from logs. This section will be hidden by default.
   6. Remove all unused fields / content to unclutter the reported issue. Remove this comment too.

   BinaryProtoLookupServiceTest.maxLookupRedirectsTest1 is flaky. It fails sporadically.

   A similar NoClassDefFoundError happened in another flaky test which is reported as #15850 . It might be possible that this is a JDK bug https://bugs.openjdk.java.net/browse/JDK-8257534 .
   
   "It may be that the initialization failed due to OOME but is being reported as a NoClassDefFoundError. " ([comment link](https://bugs.openjdk.java.net/browse/JDK-8257534?focusedCommentId=14424036&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-14424036)) 
   
   This happens more frequently with ZGC, as observed in https://github.com/apache/pulsar/pull/15762#issuecomment-1136786473

   There was a bad test that caused the problems. #15911 fixes the issue.
