[jira] [Created] (LUCENE-8991) disable java.util.HashMap assertions to avoid spurious vailures due to JDK-8205399

Chris M. Hostetter created LUCENE-8991:
------------------------------------------

             Summary: disable java.util.HashMap assertions to avoid spurious vailures due to JDK-8205399
                 Key: LUCENE-8991
                 URL: https://issues.apache.org/jira/browse/LUCENE-8991
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Chris M. Hostetter



An incredibly common class of jenkins failure (at least in Solr tests) stems from triggering assertion failures in java.util.HashMap -- evidently triggering bug JDK-8205399, first introduced in java-10, and fixed in java-12, but has never been backported to any java-10 or java-11 bug fix release...

   https://bugs.openjdk.java.net/browse/JDK-8205399

SOLR-13653 tracks how this bug can affect Solr users, but I think it would make sense to disable java.util.HashMap in our build system to reduce the confusing failures when users/jenkins runs tests, since there is nothing we can do to work around this when testing with java-11 (or java-10 on branch_8x)
