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

Which is your preferred environment for debugging?  Perhaps Eclipse, Intellij or JDB?

If you were using Intellij, you would:
1.  Click on File/Open... menu and navigate to the pom.xml file in the root of the WildFly source tree.  Wait a while for the project to be opened.

2.  While the project is being loaded, start the WildFly server with options:
  standalone.bat --debug 8787

3.  After the WildFly project is loaded into Intellij, open the Run/Edit Configurations... menu and add a remote entry for debugging, with port set to 8787.

4.  You should be able to start the debugger by clicking on Run/Debug... and choose the default that you create/update in step #3.  This will attach to the running WildFly server for debugging.

5.  Copy the exception call stack to the clipboard that you get for the "package-info".

6.  Open menu Analyze/AnalyzeStackTrace and past the clipboard contents if not already done for you.

When you click on one of the source modules mentioned in the exception call stack, the source file should open, from which you can do standard java debugging (set a breakpoint at a line) and investigate.  You should be able to open sources for most app server projects.

Hope this helps.

> 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:
