Looks like JCA is putting a wrapper around the session, if JCASessionHandle does not have
an exposed method to get the JackrabbitSession or the class definition that was used to create
the JackrabbitSession is not available to the classloader you are working in then you might
be able to do it with reflection. (IIRC Glassfish v3 is OSGi based, is JackrabbitSession exported
from its bundle ?)

In Apache Sling (also OSGi based), AccessControlUtils in the server bundle does just this,
although there isn't the added complexity of JCA.
