using ANT_OPTS to affect target java app

I have a 2gig linux 64bit OS. I am using ant 1.7.1 and jdk 1.6_31. I have a simple app that prints that asks for the size of the Maximum java heap and prints it. I am using export ANT_OPTS="-Xmx64M" but when I run my little application with ant target in build.xml, it reports 446Meg.

<target name="askmem">

        <classpath path="${build.dir}"/>

I must be doing something wrong? (I discovered from stackoverflow that with this JVM, the default heap is 1/4 total memory, which is what is happening, rather than the value I specified in ANT_OPTS.



You're forking the Java anyway, so even if ANT_OPTS did affect the java task, I don't think they'd transfer to it. ANT_OPTS is for ant itself.

If you want to control the JVM used by the forked java task, use nested <jvmargs> elements.
