GWTBridgeImpl throws com.google.gwt.core.ext.UnableToCompleteException exception

I have a large GWT application using 2.5.1 and all of a sudden I am getting the following error when run/debug in GWT hosted mode:

com.google.gwt.core.ext.UnableToCompleteException: (see previous log entries)

This happens in the GWTBridgeImpl#create(Class<?> requestedClass) method.  After the exception it builds a RuntimeException with the following error message: Deferred binding failed for 'com.google.gwt.user.client.rpc.XsrfTokenService' (did you forget to inherit a required module?)

My build is maven 3.x and I'm using IntelliJ to run in hosted mode.  This worked fine up until a couple days ago and I don't know what has changed that might cause this.  I've never seen this error/problem before.  XsrfTokenService is part of GWT so I don't know why it would be having any trouble finding/loading that.  

Does anyone have any suggestions as to what might be the cause?
