Could you try the following test? I'm wondering if it's a compression
problem or possibly a problem with BufferedInputStream..

For example, this "gunzip" program works fine for me on
several different test files...

    $ cat > gunzip.java

    import java.io.*;
    import java.util.zip.*;
    public class gunzip {
	    public static void main(String args[]) throws Exception {
		    int ch;

		    Reader r = new InputStreamReader(
			    new GZIPInputStream(System.in));
		    while ((ch = r.read()) != -1)
			    System.out.print((char) ch);
		    System.out.flush();
	    }
    }
    ^D
    $ jikes -nowarn gunzip.java
    $ gzip < gunzip.java | kaffe gunzip | diff -q gunzip.java -
    $ gzip < /etc/termcap | kaffe gunzip | diff -q /etc/termcap -
    $ gzip --best < /kernel | kaffe gunzip | diff -q /kernel -
    $ gzip --fast < /kernel | kaffe gunzip | diff -q /kernel -

Try it with some of your input files..
