Sybase jdbc driver jConnect (TM) for JDBC(TM)/7.07 GA(Build 26666) is causing many failures in Hibernate testsuite, when running on Sybase 15.5 database. It is not possible to perform basic operations, eg. inserting entity:

Error Message

could not insert: [org.hibernate.test.cascade.Child]

If the older version of jdbc driver is used "Build (26502), the problems are gone:

We should consider reverting back the driver for this release.
