When using templates (https-s2i, amq-s2i, amq-persistent-s2i) with 7.3 JDK8 image EAP pod doesn't start due to error:

ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([
    ("subsystem" => "elytron"),
    ("key-store" => "jgroups.jceks")
]) - failure description: {"WFLYCTL0080: Failed services" => {"org.wildfly.security.key-store.\"jgroups.jceks\"" => "WFLYELY00004: Unable to start the service.
Caused by: java.io.IOException: Invalid secret key format"}}

The issue seems to be a regression of CLOUD-2501 and MODULES-363.

Package `com.sun.crypto.provider` is missing from JAVA_OPTS in 7.3:
7.3 Beta JAVA_OPTS contain:
-Djboss.modules.system.pkgs=org.jboss.logmanager,jdk.nashorn.api,com.sun.crypto.provider

7.3 only has:
-Djboss.modules.system.pkgs=org.jboss.logmanager,jdk.nashorn.api

Setting as blocker because it is a regression against 7.3.Beta. This issue doesn't exist in CD18 because CD is JDK11 only and this only affects JDK8 image.
