In time of EAP 8.0 release, there was available BouncyCastle FIPS 1.x supporting just Java 11-. Now, for EAP 8.0 and 8.1, there is a new 2.x release available, supporting Java 11, 17, and 21. This new version requires a bit different configuration, especially:

• org.bouncycastle:bcutil-fips artifact is required
• provider classes need to be explicitly defined, in module adding the artifacts or in provider configuration of Elytron subsystem

Update the https://docs.redhat.com/en/documentation/red_hat_jboss_enterprise_application_platform/8.0/html-single/secure_storage_of_credentials_in_jboss_eap/index#creating-fips-140-2-compliant-credential-store-using-bouncycastle-providers_creating-fips-140-2-compliant-credential-store-using-bouncycastle-providers accordingly for EAP 8.1.

Setting priority to Blocker as it would be terrible UX for this supported use case if users were forced to find the way on their own.
