IDataModelOperation;

David,

That doesn't work for return types. If one of the arguments changed that would work provided both methods were there. But adding a method also breaks extenders of the interface (assuming the API allows this interface to be extended).

Sounds like a case of source compatibility, but not binary compatibility.
You should be able to leave in the old method, as deprecated, that would just delegate to the more specific one.
That would then maintain binary compatibility too.

I did change this back in March, but am not sure why this is broken. The change was to return an IDataModelPausibleOperation instead of IDataModelOperation, however, IDataModelPausibleOperation extends IDataModelOperation.. Why would that cause breakage?

Thank you,

Did someone delete a method from this interface? This was reported at Geronimo. I opened a bug to track it [1]
