Hello,

I have a case where a redeployment of an application causes an exception.

I have simple test "application" packaged in an ear (app.ear) with only one library (jar1.jar) included:

app.ear

    |-lib

       |-jar1.jar

jar1.jar includes a java interface class (org.jboss.test.jar1.EJBInterface).

Next a have a simple separate EJB project, containing an EJB which implements EJBInterface from jar1.jar library. This project is bundled into ejb.jar and have a deployment dependency within jboss-deployment-structure.xml like this:

<?xml version="1.0" encoding="UTF-8"?>

<jboss-deployment-structure>

    <deployment>

        <dependencies>

            <module name="deployment.app.ear" />

        </dependencies>

    </deployment>

</jboss-deployment-structure>

Deployment scenario is like this:

1. Deployment of app.ear - successfully deployed

2. Deployment of ejb.jar - successfully deployed

3. Redeployment of app.ear - app is successfully redeployed, but dependent ejb redeployment fails with an exception

This is log of this scenario:

Is this a bug in Jboss AS 7 (used version is 7.1.2) or an improper usage of EJBs?

Sample projects are attached.
