When running EAP we see javax.naming.NamingException: JBAS011843 at oracle.net.jndi.JndiAttrs.<init>

Issue

• While trying to get a datasource we get an error:

Caused by: oracle.net.ns.NetException: JNDI Package failure javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory com.sun.jndi.ldap.LdapCtxFactory from classloader ModuleClassLoader for Module "org.jboss.as.pojo:main"from local module loader @451c0d60 (roots: E:\projects\jboss\installation\EAP-6.0.0\modules,E:\projects\jboss\installation\EAP-6.0.0\myModules,E:\projects\jboss\domains\1234\servers\1234-EAP6_UNIV_univ_DBIZ\modules) 
        at oracle.net.jndi.JndiAttrs.<init>(JndiAttrs.java:159)

...

It seems that "oracle.net.jndi.JndiAttrs" can't find "com.sun.jndi.ldap.LdapCtxFactory", what sounds like a class path issue.

We already added "sun.jdk" as dependency to the oracle driver module.
We also added "sun.jdk" as global module.

Both didn't solved the problem. We also tried to add the dependency to "org.jboss.as.controller", as seen in https://community.jboss.org/thread/167524 without success.
