QueryImpl.list() closes connection
----------------------------------

                 Key: HHH-4624
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4624
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.3.2
         Environment: linux,
postgres 8.3 (same on oracle 11g, mssql 2005 and mysql)
            Reporter: Dieter Freismuth
            Priority: Critical


if an outer query.iterate() calls within an iteration step a query.list() the connection is closed and the next outer iteration step causes:
org.hibernate.exception.JDBCConnectionException: could not get next iterator result
	at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:97)
	at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66)
	at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:52)
	at org.hibernate.impl.IteratorImpl.next(IteratorImpl.java:156)

the exception is only thrown if there is no transaction!
(works fine if done within an transaction)

call hierarchy:
QueryImpl.list()
-> SessionImpl.list(String query, QueryParameters queryParameters)
-> afterOperation(success); // within finally block
-> JDBCContext.afterNontransactionalQuery( success )
-> ConnectionManager.afterTransaction()
-> ConnectionManager.aggressiveRelease() // within if ( isAfterTransactionRelease() ) {
-> ConnectionManager.closeConnection()
