jpa oneToMany查出List为空，偶现

Question

环境:springboot2+querydsl4.1.4+hibernate5.4.9+tomcat9

问题表象：有时候可以查出many的list，有时候不行。奇怪的是每次启动后，如果能查出来就一直可以查出来。如果查不出来就一直查不出来。
报错:Found shared references to a collection.

查询代码:

Pageable pageable = QPageRequest.of(demandPageQuery.getPageNum() \- 1, demandPageQuery.getPageSize());  
  
QueryResults<ProduceDemand> tuples = jpaQueryFactory.selectFrom(qProduceDemand)  
  .where(buildPredicate(demandPageQuery))  
  .orderBy(qProduceDemand.id.asc())  
  .offset(pageable.getOffset())  
  .limit(demandPageQuery.getPageSize())  
  .fetchResults();
