Refactor JOnAS javaee-api module
First of all we should work in a more modular way (see #607 (closed)).
We can keep a module that provides a all-in-one JOnAS supported apis for users, but don't use it anymore in JOnAS project. There is 3 modules using javaee-api (axis2-core, jonas-commons and jonas-services-api), for those modules we should use modular apis instead.
Then we should upgrade some of the wrapped specifications to Java EE6 apis.
