hibernate.jdbc.wrap_result_sets causes failure
We use Seam 2.1.0 GA with Oracle 10g on JBoss AS 4.2.3
When we have added hibernate.jdbc.wrapresultsets=true property to persistence.xml for Oracle Database optimization we started to get the following exception.
This might probably be related with JBoss AS or Hibernate. I have already come across a post that states that when enabled this hibernate property causes leaks.
Any ideas?
