When you click on a class file and then click "Decompile class file", the results of this seem to be cached, even if that class file is regenerated.
It appears the only way to update that cache is to clean the workspace, and then decompile again.
If this is indeed the case, could the modified date of the .class file not be used to invalidate the cache?
