          relates to

          Bug - A problem that impairs or prevents the functions of the product. DROOLS-6426 Executable model compilation failure with inline accumulate

          • 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.
