Hello All,

I hope someone has come across this before and were successfull solving
it or someone has ideas on how to solve it.

Got context
javax.naming.CommunicationException [Root exception is
java.io.InvalidClassException:
org.jboss.invocation.MarshallingInvokerInterceptor; unable to create
instance]

Process finished with exit code 0

The above is the output that I get when I try to run the file below. I
guess IntelliJ runs the following command.
