That's something I'm working on right now. Some where in the dependency chain for @Component is EntityManager that is not included in your project's dependencies (I guess scope "provided" but it can occur for other reasons).
The best we're going to be able to achieve is handle the exception better in the workbench code. We can't do much about dependency chains.
