INT-2957 Remove Unnecessary AspectJ Dependencies

Core, JDBC, JMX, JPA each had dependencies for both
weaver and rt jars. weaver is a superset of rt.

Remove dependencies on the rt jar.

Further JDBC, JPA have no dependencies on AspectJ.

Finally, the JMX dependency was compile, when only
testCompile is needed.
