          Bug - A problem that impairs or prevents the functions of the product. ENTMQBR-1995 Enabling TRACE-level logging in the broker leads to ConcurrentModificationException and failed operations

          • 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.

          Bug - A problem that impairs or prevents the functions of the product. ENTMQBR-2494 IndexOutOfBoundsException from CoreMessage.sendBuffer_1X(CoreMessage.java:313)

          • 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.
