title: in java using vtd-xml throws java.lang.UnsupportedClassVersionError
body: <p>I have an ear app with two EJB and one WEB (war) projects all using compiler compliance 1.5. In my web project I created a utility Class file that takes a byte array of an xml file and returns some string values using the vtd-xml library v2.10 and I instantiate an object of this class in a servlet. At the call of the constructor of the object (that takes a byte array) I get the error:</p>
  
  <pre><code>java.lang.UnsupportedClassVersionError: Bad version number in .class file
  </code></pre>
  
  <p>When I remove all vtd-xml related objects from the class I do not get this error. Any advice would be appreciated.</p>
  
  <p>Regards</p>
