Incorrect information on "instanceof or getClass()" page about EqualsVerifier

"Well, tools like Hibernate, and many mocking frameworks such as Mockito and EasyMock, use bytecode manipulation tricks to generate subclasses on the fly."

I don't think this sentence is correct. These frameworks simply create a subclass (that's why they require the class to not be final). That's much different than bytecode manipulation that e.g. powermock is doing.

Hi Jaroslaw,

I see your point, but I disagree. Indeed they don't change bytecode that already exists, like Powermock does, but they do generate new bytecode for the subclass that they create. As far as I'm concerned, that also counts as "manipulation" :).

(Also, I want to exaggerate the point a little bit so that people don't take for granted what happens inside Hibernate and mocking frameworks and such.)
