I thought I'd try compiling JarSpy for 4.0, but encountered this problem:
class file has wrong version 48.0, should be 47.0 (complete error below).
Grepping around the forumn here, I discovered this problem might be related to JAD as a saw thread that attributed this error to JAD staleness, however, I am not sure how just compiling sources triggers this problem.
In any case, if anyone has any pointer for me, I will try to compile / make a 4.0 of JarSpy and try to get it published for 4.0.

Please remove or make sure it appears in the correct subdirectory of the classpath.
