title: binary diff library for Java
body: <p>There are several questions about text-diff libraries for Java on SO, but none about binary diff. So here I go:</p>
  
  <p>I'm looking for a <strong>binary diff library, implemented in Java</strong>. I found <a href="http://sourceforge.net/projects/javaxdelta/" rel="noreferrer">javaxdelta</a> and <a href="http://www.bmsi.com/java/#diff" rel="noreferrer">GNU Diff port</a> but I wonder if there are some other hidden gems out there? And, maybe someone has experience with above mentioned libraries? A comparison would be super helpful.</p>
  
  <p>Finally, maybe it is helpful to know that I want to diff objects serialized with <a href="http://avro.apache.org/" rel="noreferrer">Avro</a>.</p>
