Description

SecurityManager is currently used to intercept JVM shutdown in several places. Unfortunately, it will be dropped from JDK, and so far, there has been no alternative mechanism implemented in JDK. It already results in many runtime warnings when running Cassandra 5.0 with JDK 17 (those warnings cannot be disabled).

We may wait for something provided by JDK in a future release or maybe implement a custom solution if needed.
