[Building Sakai] Entity Broker - REST getEntities - URL longer than max limit allowed

[Aaron Zeckoski]

This happens because EB is trying to be too smart for its own good. Just
change the code from returning the object directly to returning it inside
the ActionReturn wrapper and things will work the way you want (you have to
change the method signature as well).

From:
return data;
To:
return new ActionReturn(data);
