Subject Re: svn commit: r1379362 - in /lucene/dev/branches/branch_4x/solr/core/src/test/org/apache/solr/cloud: BasicDistributedZk2Test.java BasicDistributedZkTest.java

Oh man... now I know why the hell the JVM terminates with error 11...

SyncThread's interrupt causes this:

        } catch (Throwable t) {
            LOG.fatal("Severe unrecoverable error, exiting", t);
            System.exit(11);
        }
