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

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?
