error when using reserved words (JPQL aggregate functions) in entity field names and packages

[DmitryBelousov1992]

The following errors were found during migration to springboot 3.x.:

• BadJpqlGrammarException: Line 1:43 no viable alternative at input 'ie.object'; Bad JPQL grammar [select ie from ItemExample ie left join ie.object io where io.externalId = :externalId]
  for
  @query("select ie from ItemExample ie left join ie.object io where io.externalId = :externalId")
  Page findPageByExternalId(@param("externalId") String externalId, Pageable pageable);

• BadJpqlGrammarException: Line 1:63 no viable alternative at input 'ie.status=com.app.domain.object'; Bad JPQL grammar [select ie from ItemExample ie where ie.status = com.app.domain.object.Status.UP]
  for
  @query("select ie from ItemExample ie where ie.status = com.app.domain.object.Status.UP")
  Page findByStatusUp(Pageable pageable);

I am attaching an example springboot 3.x application with detailed comments and examples of errors and workarounds found in the file com.app.repo.ItemExampleRepository.
