I am working on a linkage error with a generated class. I have the class but don't have a reproduction for the problem right now. I would typically decompile with jad which will usually decompile what it can even if there is a problem, but I get this. $ jad *class Parsing acf04340b7x0102xb1d7x6a62xffffd5573ece33.class...This class has a non-class tag 1 Super class has a non-class tag 1 ItemCollectionInvalidIndex: constants: requested 26636, limit 26635 The source of the trouble comes from a huge query with many UNION ALL's. The class is huge 2.4MB. Anyone have any ideas about how to get at the contents of a corrupted class like this? Thanks Kathey
