The Java Broker Plugin API has changed to need overridden getType() method in instances of PluginFactory.
This change caused the QMF2 plugin for the Java broker in /qpid/tools/src/java to break. The following patch fixes it.

I'll commit the fix to trunk, but I'm guessing that the Java broker changes that caused this to happen might mean that it's broken on the 0.24 release branch too.
