[jboss-as7-dev] VFS question and how to extract contents of deployment root

[Scott Marlow]

One problem that I have noticed with MountHandle.getMountSource() is 
that it doesn't seem to exist for exploded deployments (AS7 ResourceRoot 
getMountHandle() returns null).

For my current (exploded) test case, 
deploymentRoot.getRoot().getPhysicalFile() seems to return the complete 
persistence unit root.
