    Description

      Functions should be implemented as pure transfomers, holding no state. But, some JSON functions violate pureness and incorrectly use inheritance and class members.

      One such example is MCOL-5607 - inheritance from JSONPathWrapper caused a race condition on substantial amount of data.

      We need to review implementations in functo_json.h and change, if needed.
