A couple of years too late, but perhaps it's because the GAE SDK on GAE's servers prevents you from skipping security checks. Are you seeing an improvement when running locally? Perhaps stepping through would reveal what actually happens. Anyway, Java 8 is coming to GAE so possibly a performance increase according to http://stackoverflow.com/questions/19557829/faster-alternatives-to-javas-reflection (not holding my breath) |

Here's a rough draft of some code that uses MethodHandles to do the setting and getting. Unfortunately, its not much faster yet. I believe using invokeExact will yield better performance but haven't gotten it to work yet.
Any thoughts or ideas?
