[jboss-as7-dev] Module classloader can't find JavaSE classes in AS7 testsuite?

[Jaikiran Pai]

I'm trying to write a test in testsuite/smoke-tests. The test is pretty 
simple and has a javax.naming.Context import in it. I keep running into 
this CNFE every time I try running it:

Apparently, the module classloader can't find the classes from the Java 
SE runtime jar? By the way, is there a document around how AS7 testsuite 
is integrated with Arquillian and jboss-modules and what are the step 
required to get a test running (it's not straightforward, as I'm seeing 
now)? I keep running into these CNFE/NCDFE issues everytime I write a 
simple test.
