Liberty server won't start when specifying java security manager in Java 24+

[gjwatts]

When trying to start a Liberty server with the security manager enabled in the bootstrap.properties file, like this

websphere.java.security

The Liberty server fails to start with messages similar to this in the console.log:

But according to our design documentation for handling the disabling of the security manager in Java 18, we are supposed to ignore the security manager request, post a message and start the server.
