Description
There are several instances where static MappingSet instances are used (for example NestedLoopJoinBatch and BaseSortWrapper). This causes instance reuse across threads when queries are executed concurrently. As MappingSet is a stateful class with visitor design pattern, such reuse causes invalid state.
