-----------------------------

             Summary: AssertionError found when using offheap BucketCache with assertion enabled
                 Key: HBASE-14660
                 URL: https://issues.apache.org/jira/browse/HBASE-14660
             Project: HBase
          Issue Type: Bug
            Reporter: Yu Li


During perf verification of HBASE-14463, found offheap BucketCache not working with assertion
enabled in hbase-env.sh:

export HBASE_OPTS="-ea -XX:+HeapDumpOnOutOfMemoryError -XX:+UseConcMarkSweepGC"
{noformat}

And the error when running PE tool is like:
