To unpack the zipped file I use the above method. On windows all works
fine. But on MAC I got the following error:
java.io.EOFException: Unexpected end of ZLIB input stream
    at java.util.zip.InflaterInputStream.fill(InflaterInputStream.java:
223)
    at java.util.zip.InflaterInputStream.read(InflaterInputStream.java:
141)
    at java.util.zip.ZipInputStream.read(ZipInputStream.java:154)
    at java.io.FilterInputStream.read(FilterInputStream.java:90)

How can I solve it?

The .available() method is not very reliable - I would avoid that.

Just read up to BUFFER_SIZE.

Have you verified that the zip file is actually readable on
MacOS X. The exception could be caused by file corruption - like
transferring the file as text instead of binary.
