I agree with all that has been said above.
We should also start preparing our users for the upcoming future without
Security Manager
and start deprecating (for "removal") affected APIs, specifically affected
classes, methods & fields
to let them know in advance there will be no alternative.
Due to time constraints It is not possible to do it all at once in one
major WildFly release in my opinion.
But the PARENT "SM deprecation" task should be created so we can
distribute its subtasks across upcoming WildFly releases.
