Inspecting .class files

Sometimes, it's hard to tell exactly what version of a class has made it onto a server. Maybe you've overridden a method in code, but your implementation never seems to be called. It could be that the actual class on the server is an old, cached version without your change.

jClassLib is a handy little util for opening up compiled .class files and seeing what's in them: fields, methods, the lot.
