I just uploaded a new version of the JAD decompiler plugin IdeaJad, which will work with 887.
I didn't have the time yet to figure out how to take better advantage of the project structure (a better doucmented API would help...), but I will do that as soon as I can. For now this at least works again!
Please let me know if something went wrong...
PS: For those of you who want to be notified of new releases - there is a feature on SourceForge that does just that. Project name is "ideajad".
