title: What would cause bash to be unable to execute a .jar written and compiled on my own machine?
body: <p>It worked fine yesterday, and it runs fine with <code>java -jar ...</code> however now when I try to run it this is the response I get:</p>
  
  <pre><code>-bash: ./Shuffle: cannot execute binary file
  </code></pre>
  
  <p>Here's a snippet of the Makefile:</p>
  
  <pre><code>$(JARFILE): $(CLASSES)
      echo Main-class: $(MAINCLASS) &gt; Manifest
      jar cvfm $(JARFILE) Manifest $(JARCLASSES)
      chmod +x $(JARFILE)
      rm Manifest
  </code></pre>
  
  <p>I'm running Mac OS X 10.6.8 and have tried reinstalling the update released yesterday Java for Mac OS X 10.6 Update 5 with no luck. Any thoughts?</p>
