[Jazzlib-developers] CRC errors using GZIPOutputStream

[Shawn F. <Sha...@te...>]

When I use the GZIPOutputStream in the jazz.util.zip package the resulting
file cannot be unzipped using gunzip. (Error msg: gunzip: test1.txt.gz:
invalid compressed data--crc error) Howerver, if I use java.util.zip it
works. Any ideas why?

The following code works once I substituted the native class
java.util.zip.GZIPOutputStream:

                try
                {
                
                    // Create the GZIP output stream
                    String outFilename = strTo;
                    java.util.zip.GZIPOutputStream out = new
java.util.zip.GZIPOutputStream(new FileOutputStream(outFilename));
                
                    // Open the input file
                    String inFilename = strFrom;
                    FileInputStream in = new FileInputStream(inFilename);
                
                    // Transfer bytes from the input file to the GZIP output
stream
                    byte[] buf = new byte[1024];
                    int len;
                    while ((len = in.read(buf)) > 0) {
                        out.write(buf, 0, len);
                    }
                    in.close();
                
                    // Complete the GZIP file
                    out.finish();
                    out.close();
                } 
                catch (IOException e)
                {
                    System.out.println(e);
                }
