Re: FileNotFoundException when loading interface ClassNode

  Unless I am missing something, that likely doesn't have much to do
with ASM. Also, I can't see how ClassReader could throw a
FileNotFoundException (not in ASM 3 API anyways).

  You need to check the value of classInternalForm and maybe also add
the leading slash to it in order to tell the classloader to look at
the exact folder/package.
