...However, you made a conclusion:...

A "hypothesis"? Yes. An "assumption"? Yes. a "conclusion"? The only "conclusion" of any importance is the fixing of the bug. For which I — and every other Hibernate user — are sincerely grateful.

From where I stand as a lowly Java coder, the implementation minutiae of precisely what line of code and in precisey which source file the bug really is, doesn't matter, frankly.

What matters is, when I call x.equals(x), if that call on x returns false, then for all intents and purposes, the bug is in x.

But of course, you need to save face. I get that. So if you prefer, I can edit the description to say something like, "It appears on the face of it that....".
