Attempting to access a global JNDI entry from a clustered Weblogic 12c environment. Any attempt to perform a lookup of an object listed under the global JNDI entry (java:global) causes a java.lang.AssertionError exception with a "Context may not be null" message. Lookup of other JNDI objects works as expected.
The following is a copy of remote test code used to reproduce the problem. It iterates through the root NameClass pairs of the InitialContext retrieved. When it performs a lookup for the "java:global" entry it throws the mentioned exception & message. It has been tested with and without SECURITY_ details with no difference.
