Subject Re: Help needed moving from 2.1.11
Date Wed, 06 Jan 2016 17:09:14 GMT
Hi Peter,

I completely agree with Christopher!
I got some 2.1.* applications running and kept up with flow of Java /
jBoss versions. Maybe there had been some issues with the XML helper
jars but I don't remember in details.

Try your luck with CentOS 7, Java 8 and Tomcat 8 ... and come back if
severe problems occur!

Greetings,

Andreas
