TestDoubleBarrelLRUCache hangs under Java 1.5, 3.x and trunk, likely JVM bug
----------------------------------------------------------------------------

                 Key: LUCENE-3235
                 URL: https://issues.apache.org/jira/browse/LUCENE-3235
             Project: Lucene - Java
          Issue Type: Bug
            Reporter: Michael McCandless


Not sure what's going on yet... but under Java 1.6 it seems not to hang bug under Java 1.5
hangs fairly easily, on Linux.  Java is 1.5.0_22.

I suspect this is relevant: http://stackoverflow.com/questions/3292577/is-it-possible-for-concurrenthashmap-to-deadlock
which refers to this JVM bug http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6865591 which
then refers to this one http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6822370

It looks like that last bug was fixed in Java 1.6 but not 1.5.
