-------------------------------
I am trying to find out why the test failed again in
https://builds.apache.org/job/HBase-TRUNK-on-Hadoop-2.0.0/469/testReport/org.apache.hadoop.hbase.master/TestTableLockManager/testTableReadLock/

{code}
getSplittableRegion() didn't appear in stack trace. We catch Exception in
getSplittableRegion() while AssertionError is a Throwable.
I think we should remove the fail() in splitThread:
{code}
} catch (Exception ex) {
LOG.warn("Caught exception", ex);
fail(ex.getMessage());
{code}
