title: $PATH variable isn't inherited through getRuntime().exec
body: <p>I'm trying to start a script by the following command in Java:</p>
  
  <pre><code>proc = Runtime.getRuntime().exec(cmd, null, fwrkDir);
  </code></pre>
  
  <p>The command, typed in a console, works flawlessly. But here it doesn't seem to find the script, even though it's path is added to the $PATH variable. Doesn't Java automatically inherit all such variables, if null is passed as Environment?</p>
