Additional Notes
related with #6056
This PR is not completed, for ReInit method instrumentation we need to check if the input is tainted and if check if the JsonParser instance is tainted and remove it from the tainted objects.
Right now there is no mechanism to allow the removal of tainted objects (This will impact performance)
