If you could send me the source code (even privately) of those two classes, I'd be interested to see. I've been working on the code for live service reloading, and though I don't think I can hit every case perfectly, I'd like to hit all the likely ones, such as whatever you've hit.
The class loader technique Tapestry uses has difficulty with access to protected (really, non-public) members (constructor, fields and methods). There's room for me to make it smarter, by doing a bit more analysis of loaded classes to see if they access non-public members of other classes (and to extend the class loading umbrella to those classes as well).
