Hello!
I have the next problem when stop jboss and run again:

RepositoryClassLoader.findClass(RepositoryClassLoader.java:630)

it stops happening when I delete the following directories from the jboss installation
jboss\server\default\tmp
jboss\server\default\work
jboss\server\default\data

and delete folder xxx.war and redeploy war files.

When I do all these, it works

When I make a change, I need to delete the directories and redeployed.

I am sure there must be a more elegant solution ¿?¿?
