    Description

      AssignmentInformation is inefficient and creates lots of garbage that increase gc pressure. It creates 3 hashmaps that each contain only 2 enum-based keys. This requires wrapper node objects, boxing/unboxing of ints, and more expensive lookups than simply using primitive arrays indexed by enum ordinal.
