> The current structure used to store the resolution information for > invokedynamic, ConstantPoolCacheEntry, is difficult to interpret due to its > ambigious fields f1 and f2. This structure can hold information for fields, > methods, and invokedynamics and each of its fields can hold different types > of values depending on the entry. > > This enhancement proposes a new structure to exclusively contain > invokedynamic information in a manner that is easy to interpret and easy to > extend.
