A simple rule - you should always remove complexity from a project and never adding it. It builds on its own so any tech you add must remove some complexity from the current project.
Warning sings for tech that brings more complexity than it is usually worth - extensive xml configs, hiding of executable code, stack traces more than 240 levels deep.
Current favorite offender - GWT - I just love when something blows up in the javascript and it just tells you - well signature object object object is not what I expect in javascript apply. And you have no idea where exactly it was generated.
So it is a KISS - the project must be of the least possible complexity to solve the problem.
