Raymond Naseef commented on AS7-6104:
-------------------------------------

Below are steps to fix the problem (this is workaround), and was able to add and remove the module after that.

I still think there is a bug, and hope this will help you to find it.  Let me know if you need any more information on this (I still have the broken version zipped, and have confirmed it is still broken when extracted).

*** Steps Leading to Problem ***

Before I added PostgreSQL module I did:

1. Added postgresql-9.1-901-1.jdbc4.jar to standalone/deployments
2. Created DataSource for this via JBoss Administration Console
3. Did the following two, not sure which one I did first:
    - removed postgresql-9.1-901-1.jdbc4.jar from standalone/deployments
    - Added main.xml & postgresql-9.1-901-1.jdbc4.jar to modules/org/postgresql/main
4. Added module using jboss-cli
5. Attempted and failed to remove the module (as explained in this issue)

***  Work Around  ***
1. Removed PostgreSQL module from standalone.xml (done using Notepad++):
                    <driver name="postgresql-driver" module="org.postgresql">
                        <driver-class>org.postgresql.Driver</driver-class>
                    </driver>
! Adding and removing the module worked fine after this
