I was able to verify the problem, kaffe is trying to decompress a zero
length file. So, when it allocates a buffer to inflate the data in,
it crashes. But, i also tried it in janosvm's newer jar file code, but
it doesn't like the format of the file, the size of the central
directory didn't match the number of entries. This may or may not be a
problem for kaffe as well. What did you use to make the jar file?
Anyways, java_util_zip_ZipFile_getZipData0 in
libraries/clib/native/ZipFile.c should prolly check for a zero length file
before calling getDataJarFile().
