          is incorporated by

          Component Upgrade - A task tracking an update to a bundled component or revision of component upstream of the project. WFLY-16254 Upgrade RESTEasy to 4.7.6.Final

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
