    I understand that maxmemory will only work with fork. Per the 
snippet I included in my original post, I am setting fork=yes in my 
javac task. And before someone says to try fork=true, I've tried that as 
well. Anyways, here is the javac part from my buildfile again.

  <target name="compile" depends="init" description="compile the source " >
    <!-- Compile the java code from ${src} into ${build} -->
    <javac srcdir="${src}" destdir="${build}" debug="on" fork="yes" 
      <fileset dir="${maindir}/external_jars" includes="**/*.jar"/>
      <pathelement path="${java.class.path}/"/>
Realized when I saw ANT_OPTS working that fork wasn't working, but I'm 
not sure why. Anyone?
And no, I'm not setting the build.compiler property.
