BUILD FAILED
what expected Specifying a wrong (insufficient) maximum memory allocation pool size in $ANT_OPTS lets you launch the ant build. The build.xml script should have rejected the build request. The condition currently checking the maximum memory allocation is : 
<condition property="memory.set">
    <contains string="${env.ANT_OPTS}" substring="-Xmx"/>
 </condition>
It doesn't check the actual value of the $ANT_OPTS variable. It might be possible to do so through the use of a custom condition : [Ant manual reference link]
