Nested/inner classes and version 1.0.0 

It's correct, nested classes are officially not supported by javassist. Anyhow, adding/changing methods and fields in nested classes works and I need it for adding logging statements. If we knew more about it, we could differentiate between cases in which it works and in which it might not work.

Why not changing the version to 1.0.0? I assume the previous committers already use this plugin in their projects. It also makes it possible to use the release plugin.
