I'm wanna be debugging an AS/EAP instance using
the binaries and attach source code that I'm using for
my project but it's not working.

Example, I have a project called ejb3-beans that uses
a User Library called eap-4.3.0.ga and within it, I have
different jars and attached source code to them.

Now, if I go to the launch configuration of the EAP 4.3
server, I go to the source tab and try to add a new path
which points to a Java Library/User Library, which is
eap-4.3.0.ga, but it doesn't work. No source code is
pulled and trying to expand the user library in the source
lookup path is unable to do so. No error is reported.
