Are there any Java Frameworks for binary file parsing?

Question

Using Preon:

public class File {

  @BoundString(match="MAGIC")
  private String header;

  @BoundList(size="10", type=Body.class)
  private List body;

  private static class Body {

    @Bound
    byte value1;

    @Bound
    long value2;

    @BoundString(size="10")
    String value3;

  }


}

Decoding data:

Codec codec = Codecs.create(File.class);
File file = codecs.decode(codec, buffer);

Let me know if you are running into problems.
