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.
