    Problem with Inheritance and javax.resource.spi.work.Work

    Andreas Wurm Newbie

      While deploying XADisk to JBOSS AS 7.1.1 i encountered some obstacles.

       

      First i encountered exceptions because the ResourceAdapter did not implement equals and hashCode. so i provided them.

       

      Header 1

      Im interested in why a resource adapter has to override equals.

       

      Also I think the validation of the WorkMethods is not correct. The WorkManager verifies if the 2 Methods of javax.resource.spi.work.Work are implemented in the class.

      In the described case both methods were implemented in a superclass of DeadLockDetector, so they were there.

      To get things working, I had to implement the methods and delegate to their superclass.

      The current implementation denies inheritance, is this the desired behaviour?
