    Description

      We run our junit tests without firing up a JVM each time.

      But some tests initialize lots of stuff in @BeforeClass and don't properly null it out in an @AfterClass, which can cause a subsequent test in the same JVM to OOM, which is difficult to debug.

      Inspiration for this was me committing Mike's cool TestPostingsFormat, which forgot to do this: then we were seeing OOMs in several jenkins runs.

      We should try to detect these leaks in LuceneTestCase with RAMUsageEstimator and fail the test.
