                 Key: LUCENE-2338
                 URL: https://issues.apache.org/jira/browse/LUCENE-2338
             Project: Lucene - Java
          Issue Type: Test
            Reporter: Uwe Schindler


Some tests catch Exceptions in separate threads and just print a stack trace - the test does
not fail. The test should fail. Since LUCENE-2274, the LuceneTestCase(J4) class installs an
UncaughtExceptionHandler, so this type of catching and solely printing a Stack trace is a
bad idea. Problem is, that the run() method of threads is not allowed to throw checked Exceptions.

Two possibilities:
- Catch checked Exceptions in the run() method and wrap into RuntimeException or call Assert.fail()
instead
- Use Executors
