Apparently inaccurate 'java.lang.UnsupportedOperationException: Illegal attempt to edit read only item' when using SQLQuery.executeUpdate
-----------------------------------------------------------------------------------------------------------------------------------------

                 Key: HHH-6329
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6329
             Project: Hibernate Core
          Issue Type: Bug
          Components: caching (L2), core
    Affects Versions: 3.6.5
         Environment: Hibernate 3.6.5, PostgreSQL, OpenJDK 7.0.144, FreeBSD 8.2
            Reporter: Alex Hayward


The following code (and, indeed, anything similar using INSERT):

SQLQuery createSequence = sess.createSQLQuery("CREATE SEQUENCE printOrder" + getId());
createSequence.executeUpdate();

results in an attempt to flush the entire L2 cache. This, in turn, results in:

java.lang.UnsupportedOperationException: Illegal attempt to edit read only item

'persister' on line 120 of BulkOperationCleanupAction is 'SingleTableEntityPersister(BoxOffice.BusinessObjects.Country)' when this happens. 'Country' is a read-only object. None have been modified. Using doWork instead works, but is unfortunately a rather awkward API for many cases.
