JBOSS wont start on jdk8
There is a known bug with JBOSS , it won’t start on JDK 8 and will be stuck on boot itself.”Brontes”…
Change standalone.bat to point to jdk 7 or apply the patch from github and build yourself.
Else use wildfly 8.

If you are not sure what all classes are loaded in currently running jvm.
Nice trick to find out what all classes are loaded in the JVM.
Try running this.
java -verbose:class CPTest |findstr URL
It will grep your class and will tell if that is loaded or not.
