Doesn't have to do with the amount of memory anything's using. It has to
do with the difference in how the command is being executed by the VM. You
can either include 'vmlauncher="no"' in your <exec> task, or include the
".bat" extension in the command name when you're running on a Win* box.
You can set it in a property that conditionally includes it -- eg:
  <condition property="loadjava" value="loadjava.bat">
    <os family="windows"/>
  <property name="loadjava" value="loadjava"/>
then reference ${loadjava} in the <exec> 'executable' attribute.
