休眠：查询计数查询时从堆栈溢出错误（从表中选择count（*））

Question

Hibernate（Hibernate版本5.0.11）条件计数查询引发stackoverflowerror：null错误，当有更多记录（如1000条以上）时出现，但在记录受到限制时则看不到。

StackTrace：

The exception contained within MappableContainerException could not be mapped to a response, re-throwing to the HTTP container

代码：

CriteriaBuilder builder = getEntityManager().getCriteriaBuilder();
CriteriaQuery<Long> criteria = builder.createQuery(Long.class);
Root<T> root = criteria.from(myclass.class);
criteria.select(builder.count(root)); 
getEntityManager().createQuery(criteria).getSingleResult().intValue();
