@jfdenise I'm no longer sure we want to update bootable jar for this 18.xbranch. This branch is meant to be used for WildFly 26. I thought that the major bump for bootable jar version was aligned with WildFly version.
Should we stick to this match:

• Bootable Jar 6.x -> WildFly 26.x
• Bootable Jar 7.x -> WildFly 27.x

This question is also relevant for wildfly/wildfly#15045

@jmesnil I didn't see your comments here and merged wildfly/wildfly#15045. That can be reverted if need be. The 7 release looked like it was basically just moving to WF 26 for its examples, which seemed valid for a 26.x test fixture. But there may be something more to it.

@jmesnil , 7.0.0.Final depends on WildFly 26, 6.0.0.Final depends on WildFly 25.0.0.Final. This is good to merge.

@jfdenise thanks!
