Change the embedded (and repackaged) version of ASM from 3.3.1 to 4.0.
Culling unused classes shaved nearly 200K off of the size of the JAR file.
This may also be a chance to analyze which ASM classes Plastic needs, and cull out the ones that are not used.
This is going to be very important, as ASM 3 doesn't understand JDK 7 bytecode.
Yeah! The 4.0 API uses Generics for all those lists of types.
