Trimming Spaces in Ant

gistfile1.xml

<!-- task to trim spaces on properties in Ant via inline javascript (requires 1.7+) -->
<!-- NOTE that properties in Ant are immutable so you must define the variable with a different name -->
<target name="trim-properties">
    <script language="javascript">
    <![CDATA[
        var myproperty= project.getProperty("myproperty");
        if (myproperty!= null) {
            project.setProperty("myproperty.trimmed", myproperty.trim())
        }
    ]]>
    </script>
        
    <echo>myproperty now set to -${myproperty.trimmed}-</echo>
</target>

Awesome!
however i just tried it out and it failed for me on openSUSE (Factory) with ant 1.9.2 and java version "1.7.0_45" (OpenJDK)... adding manager="javax" as described here: http://ant.apache.org/manual/Tasks/script.html fixed the issue for me.
