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:

Unable to find source-code formatter for language: diff. Available languages are: actionscript, ada, applescript, bash, c, c#, c++, cpp, css, erlang, go, groovy, haskell, html, java, javascript, js, json, lua, none, nyan, objc, perl, php, python, r, rainbow, ruby, scala, sh, sql, swift, visualbasic, xml, yaml

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