Set system properties in standalone-full.xml in wildfly 8.2

Question

I have added system-properties tag in standalone-full.xml, but its not working in standalone mode. However, if I add the same tag in domain.xml it's working for domain mode.

<?xml version='1.0' encoding='UTF-8'?>

<server xmlns="urn:jboss:domain:2.2">

    <extensions>
    ....
    </extensions>

    <system-properties>
        <property name="java.util.Arrays.useLegacyMergeSort" value="true"/>
    </system-properties>
</server>

According to this article on jBoss General configuration concepts

System property values can be set in a number of places in domain.xml, host.xml and standalone.xml.

Then what about standalone-full.xml?

I don't want to set it through command line and not even in java code.

In standalone it's probably too late to set it in the configuration files. You'll need to add it to the standalone.conf or standalone.conf.bat in the JAVA_OPTS environment variable. A global property like that needs to be set before anything else attempts to use java.util.Arrays.
