Compression ClassLoader

[Enoch Hsu]

Hi All,

I was looking at Compression.java and I noticed that for Snappy and LZO
compression it is using ClassLoader.getSystemClassLoader() to retrieve the
class file.
LZ4 compression is using this built in function

 private static ClassLoader getClassLoaderForCodec() {
    ClassLoader cl = Thread.currentThread().getContextClassLoader();
    if (cl == null) {
      cl = Compression.class.getClassLoader();
    }
    if (cl == null) {
      cl = ClassLoader.getSystemClassLoader();
    }
    if (cl == null) {
      throw new RuntimeException("A ClassLoader to load the Codec could not
be determined");
    }
    return cl;
  }

Is there a reason for the differences between using getSystemClassLoader
and getClassLoaderForCodec?
Seems like the getClassLoaderForCodec method of retrieving compression
class files is more user friendly?

Thanks,
