System property "jboss.server.log.dir" not working for custom logger in EAP 6.1.

Issue

• Variable is correctly set in the boot.log but in custom logger not visible.
• Internally resolve the Property "jboss.server.log.dir" to get the standard JBoss logging directory. But in EAP 6.1 the property is null.

private boolean configure() {
String logDir = System.getProperty("jboss.server.log.dir");

Following is the custom logger

<subsystem xmlns="urn:jboss:domain:logging:1.2">
            <custom-handler name="CUSTOM_DAILY_ROLLING_HANDLER_OTHER" class="xxx.yyy.zzz" module="x.y.z">
                <level name="DEBUG"/>
                <formatter>
                    <pattern-formatter pattern="%d{HH:mm:ss,SSS} %-5p [%c] (%t) %s%E%n"/>
                </formatter>
                <properties>
                    <property name="maxNumberOfDays" value="30"/>
                    <property name="logDir" value="jboss.server.log.dir"/>
                    <property name="fileName" value="other.log"/>
                    <property name="compressBackups" value="true"/>
                </properties>
            </custom-handler>
