---------------------------------------

             Summary: Index out of bound when using FramedLZ4CompressorOutputStream or BlockLZ4CompressorOutputStream
                 Key: COMPRESS-401
                 URL: https://issues.apache.org/jira/browse/COMPRESS-401
             Project: Commons Compress
          Issue Type: Bug
          Components: Compressors
    Affects Versions: 1.14
            Reporter: Manuel Pagliai


The following java snippets fail with an index out of bound exception

    FileInputStream fis = new FileInputStream(new File("P:\\Data\\orders_5m.csv"));
        FileOutputStream fos = new FileOutputStream(new File("P:\\Data\\orders_5m.csv.lz4"));

        BufferedOutputStream out = new BufferedOutputStream(fos);
        FramedLZ4CompressorOutputStream lzOut = new FramedLZ4CompressorOutputStream(out);
        
        final byte[] buffer = new byte[1 * 1024 * 1024];
        int n = 0;
        while (-1 != (n = fis.read(buffer))) {
            lzOut.write(buffer, 0, n);
        }
        lzOut.close();
        fis.close();


Also the Lz4 Example in https://commons.apache.org/proper/commons-compress/examples.html contains
errors
