Within the WildFly Elytron subsystem the following method contains a utility to detect if FIPS has been enabled so we can avoid violating some FIPS requirements: -

org.wildfly.extension.elytron.SSLDefinitions.getFipsSupplier()

The method that is being used for this is no longer present in Java 17. Currently, we "fail safe" and just log a message if we could not detect the availability of FIPS. We need to determine how to detect FIPS for Java 17+.
