The jberet-core module should not depend on the javaee.api module

The javaee.api module is just a convenience wrapper around the various EE API modules it depends on and exports. The org.jberet.jberet-core module depends on this; it should be updated to depend on the specific APIs it need.

Depending on javaee.api is problematic because in a server that has been slimmed using Galleon we only want to depend on modules that are actually needed and not pull in other API.
