Use something like below (512m <=> 512 Megabytes) for your compiles that
requires lots of memory 'cause involves lots of code:

    <javac srcdir="${src}"
           source="${javac.sourceflag}" >

  ANT_OPTS - command-line arguments that should be passed to the JVM.
  For example, you can define properties or set the maximum Java
  heap size here. 

(Probably deserves an FAQ entry, though.)
