Chapter 5. Unsupported, deprecated, and removed functionality

The following features are not supported by Red Hat.

EAP operator

Red Hat JBoss Enterprise Application Platform 8.0 Beta does not support the EAP operator. You cannot deploy your JBoss EAP applications using the EAP operator. For more information, see JBoss EAP Operator Support Policy.

Logging

JBoss EAP 8.0 Beta does not support Apache Log4j version 1 APIs. If your applications do not package log4j.jar and Log4j configuration as part of the application, then you must update them. For more information about migrating or updating your applications, see the Red Hat Knowledgebase solution Migration: Apache Log4j version 1 is no longer provided in EAP 8.

Some features are deprecated with this release. This means that no enhancements will be made to these features, and they might be removed in a future release.

Red Hat will continue providing full support and bug fixes under our standard support terms and conditions. For more information about the Red Hat support policy, see the Red Hat JBoss Middleware Product Update and Support Policy located on the Red Hat Customer Portal.

For details of which features have been deprecated, see the JBoss Enterprise Application Platform Component Details located on the Red Hat Customer Portal.

JDK 8

JDK 8 has been removed from Red Hat JBoss Enterprise Application Platform 8.0 Beta. JDK 11 or JDK 17 is now required.

Legacy security realms

The legacy security realms have been removed from JBoss EAP 8.0 Beta. Use the security realms provided in the elytron subsystem instead.

For more information, see the Securing applications and management interfaces using an identity store, and Securing applications and management interfaces using multiple identity stores guides.

Picketbox

PicketBox has been removed from Red Hat JBoss Enterprise Application Platform 8.0 Beta. Any legacy security configurations must be migrated to the elytron subsystem. For more information about migrating your security configurations to the elytron subsystem, see Migrating to Elytron.

PicketBox vault

PicketBox vault has been removed from JBoss EAP 8.0 Beta. Use the credential store provided by the elytron subsystem to store sensitive strings instead.

For more information, see Credentials and credential stores in Elytron in the Secure storage of credentials in JBoss EAP guide.

PicketLink Subsystem

The PicketLink subsystem has been removed from JBoss EAP 8.0 Beta. Use Red Hat Single Sign-On instead of the PicketLink identity provider, and the Red Hat Single Sign-On SAML adapter instead of the PicketLink service provider.

For more information, see the following resources:

discovery-group and broadcast-group resources

Red Hat JBoss Enterprise Application Platform 7.4 removed the discovery-group and broadcast-group resources. These resources are still removed in JBoss EAP8.0 Beta.

Additionally, Red Hat JBoss Enterprise Application Platform 7.4 reduced the impact to its web console by replacing all instances of discovery-group and broadcast-group resources with jgroups-discovery-group and socket-discovery-group resources.

JBoss EAP 7.3 deprecated the following resources in the messaging subsystem:

JBoss EAP 7.3 replaced these deprecated resources with jgroups-discovery-group and socket-discovery-group resources. Each deprecated resource included an attribute from each replacement resource, with one attribute set to null and the other attribute set to a value greater than 0. These settings caused both discovery-group and broadcast-group to remain active, but still assign all their functionality to the jgroups-discovery-group and socket-discovery-group resources.

Quickstarts

The following outdated or redundant quickstarts have been removed from JBoss EAP 8.0 Beta:

Red Hat Single Sign-On Client Adapter

Red Hat JBoss Enterprise Application Platform 8.0 Beta does not provide the Red Hat Single Sign-On Client Adapter. Use the new elytron-oidc-client subsystem to secure applications deployed to JBoss EAP with OpenID Connect (OIDC).
