run.args.extra not working?

Ah I found it, its my main build.xml. I've modified as following:


Code:

<?xml version="1.0" encoding="UTF-8"?>
<!-- You may freely edit this file. See harness/README in the NetBeans platform -->
<!-- for some information on what you could do (e.g. targets to override). -->
<!-- If you delete this file and reopen the project it will be recreated. -->
<project name="asset-management-nb" basedir=".">
    <description>Builds the module suite my-nb-app.</description>
    <import file="nbproject/build-impl.xml"/>

    <target name="build-launchers" depends="suite.build-launchers">
        <replace file="build/launcher/etc/${app.name}.conf" token="--branding my-nb-app -J-Xms24m -J-Xmx64m" value="--branding my-nb-app -J-Xms128m -J-Xmx2048m"/>
    </target>
</project>
