Evidently, things got deeply scrozzled in build 939 with inspections. InspectionGadgets now reporting more or less random errors on the batch inspection report, with no explanation. I'd love to fix this issue, but I am unable to load idea.jar in 939, as it gives an exception and eats up all available memory trying to parse it. Even if I was inclined to fix this issue without using IDEA (which I'm not), I also can't get build IG using command-line Ant anymore, as I get some sort of class-file version error. Clearly the universe doesn't want this plugin to work anymore.
In short, InspectionGadgets is unusably hosed in build 939, and I'm completely unable to fix it. I have pulled it from my plugins directory, and I suggest that you do the same, until further notice. Sorry for the inconvenience.
BTW, The new inspection report is lovely. Can I specify my own version of the "little man" icon to distinguish builtin and IG inspections, or is that hardcoded?
