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