I keep getting this casting error and I cannot figure out the issue. The problem is fter I get this error I cannot do anything with my DB, and I have to drop the whole schema and recreate it. I am using CDO 4.3 Hibernate and MYSQL on Kepler. This only happens for my model, I cannot reproduce it with test. but I cannot figure out what in my model could have caused this. Also, I am using a CDO model, I cannot convert my model to a CDO model as I am extending a class that is not CDO and I cannot extend two classes.

Another update on this I checked the string value that is passed to the method is "oid1" and the target is CDORevisonImpl

It is on my legacy model. and happens when I am changing the resource the second time I load it.
