我有一个具有以下查询方法的存储库

@Query("SELECT contents FROM Content contents JOIN contents.mails m WHERE m IS NOT EMPTY AND contents.startDate <= :startDate")
Set<Content> findAllByCreateDateIsBeforeAndMailRecipientsIsNotEmpty(@Param("startDate") Instant startDate);

问题是在我从Spring 2.7.5更新到3.0.1之后，出现了以下错误，并且Spring应用程序无法启动。

Error interpreting query 
[SELECT contents FROM Content contents JOIN contents.mails m WHERE m IS NOT EMPTY AND contents.startDate <= :startDate]; 
this may indicate a semantic (user query) problem or a bug in the parser 
[SELECT contents FROM Content contents JOIN contents.mails m WHERE m IS NOT EMPTY AND contents.startDate <= :startDate]

class org.hibernate.query.sqm.tree.domain.SqmSetJoin 
cannot be cast to class 
org.hibernate.query.sqm.tree.domain.SqmPluralValuedSimplePath 
(org.hibernate.query.sqm.tree.domain.SqmSetJoin and 
org.hibernate.query.sqm.tree.domain.SqmPluralValuedSimplePath 
are in unnamed module of loader 'app')

在我从WHERE STATEMENT中删除m IS NOT EMPTY后，应用程序启动并正常工作，但查询并不像它预期的那样。
注意：内容和邮件是Spring中定义的经典的多对多关系，数据库是Oracle v.19。
可以做些什么呢？
