[JENKINS-68018] File leak detector socket support for Java 17+

[jenkins-infra-bot]

See jenkinsci/lib-file-leak-detector#86. In Java 17+, the implementation of sockets has changed fundamentally; therefore, the current approach does not work anymore. In #84, Listener was adjusted to degrade gracefully if the expected fields in SocketImpl are not available. Socket support likely needs a complete rewrite for Java 17+.

  Does this mean that open sockets are not detected in Java 17?  Is a fix for Java 17 sockets available in any release?

  Nope. A pull request to rewrite socket support for Java 17+ would be welcome.
