title: Ant is not following "executable" attribute for javac
body: <p>I've been trying to generate a build using Ant version 1.9.4. I've Java 1.6, 1.7 and 1.8 installed on my server. I want to specifically compile my java project against Java 1.6. so, I've included fork = "yes" &amp; executable = "/etc/alternatives/java_sdk_1.6.0/bin/javac"</p>
  
  <p>But, still running ant takes java1.8 for compiling java files. How do ensure that my Ant compiled output is against 1.6.</p>
  
  <p>Note: I've also included source &amp; target as 1.6.</p>
