CLI client in jconsole doesn't work with JDK11

Details

    Description

      CLI client in jconsole doesn't work with JDK11.

      JConsole uses CLI. CLI uses WildFlySecurityManager (Elytron 1.5.4.Final). WildFlySecurityManager uses sun.misc.Unsafe. Unsafe works just with adding of --add-modules=jdk.unsupported to JConsole:

      But "jdk.unsupported" module is not a correct fix.

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
