You should be able to use Java's remote debugging facility. I've done something similar before and I would simply set a breakpoint in the test that failed. This page describes how to set up remote debugging in eclipse. How you enable debugging depends on the app server you're using.

You can connect to a remote Java EE app server with IntelliJ and step through the code line by line.
