the log shipper thread is still running causing the hang in the master

org.apache.derby.impl.store.replication.slave.SlaveController$SlaveLogReceiverThread.run(SlaveController.java:476)
The SlaveLogReceiver thread is hanging on the read method of the socket it is
listening on causing the hang on the slave.
The questions I am searching for answers now is
1) Why is this happening only in the embedded mode?
2) How does turning authentication on affect this?
