  5. javac Ant Task out of memory Exception[ Go to top ]

    Specify the Initial Memory Size also .
    srcdir="src"
    destdir="build/classes"
    classpathref="classpath" memoryInitialSize="1024m"/
    memoryMaximumSize="1024m"/>

    Also you can check  what point your ant task is failing by specifying -v option for the ant task ( Example ant -v -f build.xml  bundle.release)
