> When a procedure with dynamic sql is rerun the cloning of the group context allows for the same linked list to be modified by multiple threads leading to errors, which typically resemble a null pointer exception (for example at QueryResolver line 259 due to a null group). The cloning also allows for the group context groups to grow in number as the locally scoped groups are re-added.
