title: SQL Server JDBC Exception
body: <p>When using ANT to build my Java application I keep getting this error. I have tried multiple times to use SQLJDBC.JAR and SQLJDBC4.JAR but continually receive this error message. I am completely stumpped why this error is received even after upgrading to sqljdbc4.jar.</p>
  
  <pre>
  [javadoc] java.lang.UnsupportedOperationException: 
      Java Runtime Environment (JRE) version 1.6 is not supported by this driver.
      Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.
