PropertyAccessException when caching results from a Query with a ResultTransformer that as 1 value per row

PropertyAccessException is thrown when all of the following are true:

• Query has a ResultTransformer

• results are cached before being transformed

• each result has a single value

This is reproduced by:

• HqlQueryCachePutResultTransformerTest.testOneSelectNewListFailureExpected(), which has:
  s.createQuery( "select new org.hibernate.test.querycache.StudentDTO(s.name) from Student s order by st.studentNumber" );

• HqlQueryCachePutResultTransformerTesttestAliasToBeanDtoOneArgListFailureExpected(), which has:
  s.createQuery( "select st.name as studentName from Student st order by st.studentNumber" )
  .setResultTransformer( Transformers.aliasToBean( StudentDTO.class ) );
