I do not think that the library should limit the compression ratio. Large compression ratio is legit. For example, compressed file of size 1 GiB consisting of zeros has the compress ratio 1030 (and I suppose it is even larger if use bzip2 or lzma compressions). If this is a problem for your program, your program should make a decision what ZIP files should be rejected. I suggest to close this issue as "not a bug".
