How to repeat:
On the content tab of EAP5 server, create new JAR file, (i uploaded https://svn.jboss.org/repos/embjopr/trunk/jsfunit/testdata/ejb3/BasicEJB3.jar ) as a Library. Select "New Channel" option and give the new channel a name (I used "jeffchannel"). Continue to submit the new jar file.
Now go to the Subscriptions subtab, click on the channel name you just created, find the package you just uploaded, select it and click "Install Packages". Nothing happens.
Now go to the New tab, you'll see the package still available for deployment. select it and click "Deploy selected". The history will show success but nothing happens on the agent nor the EAP server.
