          Bug - A problem that impairs or prevents the functions of the product. AS7-4975 XA datasources memory leak

          • 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.

          is related to

          Feature Request - Feature requests from customers and/or users JBTM-1255 JBoss AS 7.1.1 Final XA datasources memory leak

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.
