Issue

• Javadoc of the disposeRuntimeEngine method in org.kie.api.runtime.manager.RuntimeManager is confuse. Do you need to call disposeRuntimeEngine method under JTA Transaction?

     * Disposes <code>RuntimeEngine</code> and notifies all listeners about that fact.
     * This method should always be used to dispose <code>RuntimeEngine</code> that is not needed
     * anymore. <br/>
     * ksession.dispose() shall never be used with RuntimeManager as it will break the internal
     * mechanisms of the manager responsible for clear and efficient disposal.<br/>
     * Dispose is not needed if <code>RuntimeEngine</code> was obtained within active JTA transaction, 
     * this means that when getRuntimeEngine method was invoked during active JTA transaction then dispose of
     * the runtime engine will happen automatically on transaction completion.
