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.

It might be related to the classload order ... see http://stackoverflow.com/a/26829874/453389 — shonky linux user, Jun 09 '15 at 08:08
Note that this question is in relation to a property used by the Java Platform itself! — Konstantin, Dec 21 '18 at 07:55

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.

If you have started the Wildfly server with standalone-full.xml instead of standalone.xml(the default) than this should be reflected in the start of the server:

standalone.sh -b <hostIP> -c standalone-full.xml -Dorg...

Then this will have effect on first start.

If you change something in this config file, you will need to reload Wildfly(configuration) from jboss cli:

[standalone@localhost:9990 /] :reload

For Wildfly 10 it's working nontheless. I was able to read the property for an instance started with the standalone-full.xml containing some properties.

The manual must be outdated then I guess? Because even Wildfly itself inserts a new property in the standalone-full.xml when using the Wildfly admin webinterface: http://localhost:9990 > Configuration > System Properties (Wildfly will add the property of course to the xml config which was used to start the instance). That's enough proof for me.

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