Scott Marlow commented on WFLY-1406:
------------------------------------

Try using jdb instead, its much easier to get going and doesn't require the source to be used (you can set break points on class line numbers or class method names).

jdb -attach 8787

http://www.packtpub.com/article/debugging-java-programs-using-jdb is one tutorial on using JDB, but http://docs.oracle.com/javase/1.3/docs/tooldocs/solaris/jdb.html might be enough.

If you ever used a c debugger on sunos or solaris, using jdb is very similar.  Its a pain that you have to enter "step or next" commands on the keyboard but for lite debugging, it usually is good enough.

> I tried the snapshot which contains Hibernate 4.3.0.Beta2. However, package-info.java files are causing problems. For instance, the package de.shop.artikelverwaltung.domain has a package-info.java which causes a NoClassDefFoundError:
> "IllegalName: de/shop/artikelverwaltung/domain.package-info". Please see the stacktrace below.
> Here is an example for package-info.java which was working with WildFly 8.0.0.Alpha1:
