Marek Kopecký commented on WFCORE-1120:
---------------------------------------

[~jamezp]: Thank you for you fix, it seems to be useful for java.net.preferIPv4Stack property. But is your patch useful also for java memory properties like [-Xms64m or -Xmx512m|https://github.com/wildfly/wildfly-core/blob/master/launcher/src/main/java/org/wildfly/core/launcher/AbstractCommandBuilder.java#L48]? If arquillian.xml defines -Xms1024m, default value should be replaced. This allows memory tuning of java memory during TS runs, it could be useful on slower machines ...

> *Description of problem:*
> Domain tests "-Djava.net.preferIPv4Stack=true" also with IPv6 profile. This property is set in AbstractCommandBuilder of WildFly-Core:
> https://github.com/wildfly/wildfly-core/blob/master/launcher/src/main/java/org/wildfly/core/launcher/AbstractCommandBuilder.java#L50
> There should be option for disable of this option in arquillian.xml file. And testsuite should use this option with IPv6 profile.
> *How reproducible:*
> Always
> *Steps to Reproduce:*
> # ./integration-tests.sh -fae -Dmaven.test.failure.ignore=true -Dnode0=$MYTESTIPV6_1 -Dnode1=$MYTESTIPV6_2 -Dipv6 -Dts.manualmode -Dtest=OutboundLdapConnectionTestCase -DtestLogToFile=false -Djboss.dist=$JBOSS_DIST -Dts.noSmoke
