Usually I see this when deploying my RA:
21:30:53,599 INFO org.jboss.as.server.deployment#start JBAS015876: Starting deployment of "filesystem.rar" (runtime-name: "filesystem.rar")
21:30:53,745 INFO org.jboss.as.connector.deployment#bindConnectionFactory JBAS010406: Registered connection factory java:/Filesystem

21:30:53,764 INFO org.jboss.as.connector.deployment#transition JBAS010401: Bound JCA ConnectionFactory [java:/Filesystem]
21:30:53,822 INFO org.jboss.as.server#handleResult JBAS018559: Deployed "filesystem.rar" (runtime-name : "filesystem.rar")

Because JCA 1.7 was introduced to head at github I changed header of ra.xml to 1.7 version.
But then I no longer see the line
21:30:53,764 INFO org.jboss.as.connector.deployment#transition JBAS010401: Bound JCA ConnectionFactory [java:/Filesystem]

I did not specify the <outbound-resourceadapter> in ra.xml.
Another adapter is working fine after version upgrade.
So I added the <outbound-resourceadapter> also to the now failing one.
But this gives this now:

Adding also <reauthentication-support>false</reauthentication-support> solves this NPE, the RA gets deployed and bound to JNDI again.
