package javax.security.auth.login: already loaded
Hi,
I recently upgraded from 3.2.1 to 3.2.3 and I am getting the following deployment error loading a ear file.
java.lang.NoClassDefFoundError: javax/security/auth/login/LoginException
There are 3 ear files, say A, B, and C. Each is loaded in its own class loader. The jaas.jar file is included in all of these ear files.
When I browsed through the class loading trace, I found this error...

I can see that the class is loaded previously and if I am not mistaken its in a different class loader than the above.
Here is the log where jboss loads the class prior to the above error...

I am not sure what needs to be changed to make this work. One interesting thing I found out was replacing the jaas.jar file with jboss-jaas.jar file did not throw any errors, and the deployment was successfull.
Thanks in advance,
