This issue affects the latest productized Bootable JAR plugin, i.e. 6.1.2.Final.

An modular JDK export - i.e. jdk.naming.dns/com.sun.jndi.dns is not added to the JAR manifest when building a Bootable JAR which is configured with the <cloud/> option.

Such export is needed in order to let the custer member discovery mechanism work properly with modular JDK based images (e.g.: the OpenJDK17 image).

Upstream issue: https://github.com/wildfly-extras/wildfly-jar-maven-plugin/issues/301

The agreed resolution is to have another micro version of the 6.x plugin released and productized for EAP XP4 Bootable JARs, while WIldFly Bootable JARs can be built with the 7.x version of the plugin that contains the fix already.
