Jan Blizňák commented on WFWIP-225:
-----------------------------------

Ok after more precise investigation it seems that we are only missing the export at standalone.conf for GC_METASPACE_SIZE, probably here https://github.com/wildfly/wildfly-cekit-modules/blob/master/jboss/container/wildfly/galleon/fp-content/java/added/src/main/resources/packages/wildfly.s2i.java/content/bin/java-conf.conf

The only effect of it missing there is that XX:MetaspaceSize value is read from JAVA_OPTS where the default value for this is {{JAVA_OPTS="-Xms1303m -Xmx1303m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true"}}. This results at tiny difference:

with {export GC_METASPACE_SIZE=${GC_METASPACE_SIZE:-96}}:
{code:java}
-XX:MetaspaceSize=96m
{code}
without the export:
{code:java}
-XX:MetaspaceSize=96M
{code}

It broke our strict tests but this is not a big issue, just somewhat inconsistency that could be enhanced, lowering to minor priority.

> In CLOUD-3270, some changes were made to be able to override jvm metaspace value but current image docker-registry.upshift.redhat.com/kwills/eap-cd-openshift-rhel8:18.0-EAP7-1216 doesn't have it.
