      Description

      LuceneJUnitResultFormatter uses a lock to buffer test suites' output, so that when run in parallel, they don't interrupt each other when they are displayed on the console.

      The current implementation uses a fixed directory (lucene_junit_lock/ in java.io.tmpdir (by default /tmp/ on Unix/Linux systems) as the location of this lock. This functionality was introduced on SOLR-1835.

      As Shawn Heisey reported on SOLR-2739, some tests fail when run as root, but succeed when run as a non-root user.

      On #lucene IRC today, Shawn wrote:

      (2:06:07 PM) elyograg: Now that I know I can't run the tests as root, I have discovered /tmp/lucene_junit_lock. Once you run the tests as user A, you cannot run them again as user B until that directory is deleted, and only root or the original user can do so.
