TomEE throwing IndexOutOfBoundsException

问题

I am trying to deploy a Vaadin/JEE6 application to TomEE.

The following exception is thrown during deployment:

org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/myapp]]

I must admit I've no idea why this exception may be thrown. Before digging into the TomEE code, I would like to ask if anyone here ever stumbled across this exception and could give me a hint where to look for errors.

回答1:

Seemed to be a combination of buggy beta-1 and buggy project setup. See TomEE-51 for details.
