title: Crash when calling autoSizeColumn on worksheet, when run under Linux (Servicemix)
body: <p>I've written module that generates excel, and deployed it under Servicemix. In Windows environment everything is fine, but under Linux Servicemix unexpectedly crashes on following call:</p>
  
  <pre><code>    for (short i=0;i&lt;=3;i++) {
          log.trace("AutoSize column {}", i);
          worksheet.autoSizeColumn(i);
      }
  </code></pre>
  
  <p>I'm using POI version 4.2-FINAL, FuseESB 4.2, Java 5.0. There are, however, no hs_err*.pid files. Servicemix logs ends on first autoSizeColumn call. </p>
  
  <p>Did anyone met such behaviour and know, how it is caused and how to come this around?</p>
