Maybe it would be better to fake a low SDK version. Maybe decompressors check it and reject too big versions as unsupported. I'm guessing here, I have no idea about the real-world implementations. > - I am not sure if the constraints on compression parameters > mentioned at [1] would ever trip in decompressing ZIP files. > Probably not in practice. The spec doesn't mention them, alas. The Java version doesn't support LZMA1. If it is adapted to support it, there's no similar limit of lc + lp <= 4 as there is in liblzma because in Java the arrays are allocated one by one. -- Lasse Collin | IRC: Larhzu @ IRCnet & Freenode
