title: Java Array in Jruby
body: <p>I have a Java lib that I am pulling some data out of.</p>
  
  <p>It out puts a 3D array. However I can not do anything with it.</p>
  
  <pre><code>[[D[]@5615a6e0
  </code></pre>
  
  <p>is the response I get. I have tried mapping it:</p>
  
  <pre><code>{ |arr| arr.map { |arr| arr.to_a } }
  </code></pre>
  
  <p>but i get nothing out, What is the best way to parse this java array for ruby use?</p>
