title: What is causing the Java VM on OS X to crash with "Invalid memory access of location java"?
body: <p>The full message that I got on the console is:</p>
  
  <pre><code>Invalid memory access of location 00000000 eip=0117f7e1
  Bus error
  </code></pre>
  
  <p>I don't remember seeing the Java VM crashing with this before, and I wasn't running code that was particularly new. Have you ever seen this before?</p>
  
  <p>I got this error running Java 1.5 on OS X. The precise version is:</p>
  
  <pre><code>java version "1.5.0_19"
  Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-b02-304)
  Java HotSpot(TM) Client VM (build 1.5.0_19-137, mixed mode, sharing)
  </code></pre>
