title: xception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: PermGen space
body: <p>When executing a java desktop application I get a <code>java.lang.OutOfMemoryError: PermGen space.</code></p>
  
  <p>I have tried increasing java heap size, passing this argument to the VM:</p>
  
  <pre><code>-Xmx1g
  </code></pre>
  
  <p>But it keeps failing. It doesn't fail if any other colleague runs it in their computers...</p>
  
  <p>What could be causing this?</p>
