Errai 2.4.0.Final - Strange exceptions in JBoss 7.2/WildFly 8 Beta 1

hr.stoyanov Oct 7, 2013 4:38 AM

Hi,

I am getting some inexplicable exceptions with Errai 2.4.0.Final when deploying to JBoss 7.2/WildFly 8.Betra1. I wasted quite a bit of time on this wild goose chase, when thanks to Google I came across the "Known Issues" in this post:

http://mpickhan.de/2013/09/28/run-erraigwt-with-gradle/

where it is stated that the Errai team is aware of the issue and ignores it.

I find it hard to believe that the JBoss Errai team will ship product that throws exceptions under JBoss 7.2. At least, this should have been mentioned in the release notes for Errai 2.4.0 or somewhere in the docs. But is not! Nor is an emergency fix published.

So, I assume I am doing something wrong here - can anyone point me to what I am doing wrong? The issue is also present when deploying to WildFly8 Beta 1.

Do you need to add app server specific support to your deployment? (For example, errai-jboss-as-support for AS7)
