Stuart Douglas commented on WFLY-2719:
--------------------------------------

This is already fixed in Undertow upstream, should be upstream soon. You can just disable session persistence as a workaround.

> A NullPointerException occurs on the first request to the WildFly AS if the war package already exists and has been deployed via maven on both occasions causing an 500 Internal Server Error on the client.
> Removing the beans.xml from WEB-INF stops the error from occurring but services aren't injected.
