Answer 1

The message about version 50.0 means that the class files were compiled for JDK 1.6 (or greater, when others are released). The JVM that's reading that file must not be 1.6.

Compile in JDK 1.6 and running on lower version than Java 6

Please refer here for similar kind of issue.

Answer 2

Can you check the version of Java you are using? You have to know that JBoss EAP 6.x must be run on JDK 6 or JDK 7.
