Re: Dependeny on javax.swing

Well, if you can get them to whitelist those, purely data-structure manipulating interfaces and classes that are found in javax.swing.tree.*, that'd be a start. As I said, something similar ought to exist in java.util.* anyway...

However, if that obstacle is alleviated, we'll probably still run into this problem with GAE having a broken reflection implementation:

We are clearly not strong enough to get Google to do anything, but Sun is fairly strict about defending the Java trademark against abuse. Sun *can* get Google to fix this.
