title: "Unable to locate tools.jar" when running ant
body: <p>When running ant, I get the following message:</p>
  
  <p><code>Unable to locate tools.jar. Expected to find it in C:\Program Files\Java\jre6\lib\tools.jar</code></p>
  
  <p>I have JAVA_HOME set to <code>C:\Program Files\Java\jdk1.7.0_02</code>, PATH includes <code>C:\Program Files (x86)\Java\jdk1.7.0_02\bin</code>, CLASSPATH includes <code>C:\Program Files (x86)\Java\jdk1.7.0_02</code>, and ANT_HOME is set to <code>C:\ant</code>.</p>
  
  <p>It seems that ant is ignoring all of these settings and looking for the tools.jar somewhere else.  There are no environment variables which point to the jre6 path.  Any ideas why?</p>
