      When Hibernate executed a cacheable query using a <classname>ResultTransformer</classname>, it attempted to cache the results. However, the data had the potential to be modified so that Hibernate could not read it.

      PropertyAccessException was thrown when all of the following are true:

      * The query has a ResultTransformer
      * Results are cached before being transformed
      * Each result has a single value

      This issue is fixed by introducing three new API calls:
      org.hibernate.transform.AliasedTupleSubsetResultTransformer
      org.hibernate.transform.CacheableResultTransformer
      org.hibernate.transform.TupleSubsetResultTransformer.

      Refer to the Hibernate Javadoc for more details.

      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 ) );
