Looking at the OutputConnectorFactory code, it seems there are two
problems. The exception handling has a bug assuming a null value won't
be passed. Line 149 says "throw (ManifoldCFException) z;" where z is
null. The main problem is why registering my connector is now producing
an InvocationTargetException? and it wasn't a problem before?
public DupFinderConnector() throws ManifoldCFException {
Logging.connectors.log(Level.ALL, "DupFinder Version 1.0.0");
calendar = Calendar.getInstance();
hashGen = new HashsumGenerator();
}

Any idea why I would get this failure on registering my connector.
Hadn't seen it before. I was trying to setup a new system and was
issuing commands to setup the database. Note I was able to register
Null Output and File System connectors without error.
