Unfortunately you can't mix lazy loading with serializable caches....
This is not an iBATIS problem, but more of a CGLIB and/or Java problem. I'm sure we could find some crazy means of managing this, but I'd rather not. The real solution is to tell Sun that we want dynamic proxies for classes, just like we have for interfaces....and we want them to be serializable.

I'm using a serialized cache with result maps that contain a discriminator.
This fails with NotSerializableException unless I set
lazyLoadingEnabled="false". Is this expected?
What effect does setting lazyLoadingEnabled=false have?
