AS 6 (trunk) recently upgraded to the latest Hibernate core release (3.6.0.CR1 and will use 3.6.0 final when available). This was needed for the AS 6 integration with Infinispan (currently ongoing effort on a branch). This caused an AS unit test failure due to the Seam DVD Store example including a Hibernate search jar version that expects to find a method that is no longer in Hibernate core.
There should be a new Hibernate search release soon that no longer depends on the above mentioned method (see error below).
Please make whatever changes are needed to sync up with the Hibernate 3.6.0 core that AS 6 is using.
