I'm not sure I understand. With type erasure it should work, right? So it is our bug that it doesn't? If yes, should that be resolved before we can pull the generics out of comments?

Comment wasn't clear (will update) - but this actually fails both with and without the change.

Well because the body of Object.equals for GOTO functions looks like
to_return = NONDET(_Bool);
return to_return
Will raise an issue as if two objects are actually the same it should work!

Which is just a property of not using the any models for java.lang.Object - will see if I can find out how regression tests are meant to use the core models. Thanks for making me dig a bit!

Forgot to post here - TG CI has failed (some generic types are not printing correctly) and this has fallen below another item in my priority list so is currently stalled. I endeavour to get back to this PR this week. |

Though this wasn't the problem, makes the tests more robust as more than one type used in specialising the same generic type.
The symex_target_equation will merge two types who differ only in generic specialisation losing the specialisation information. This ensures that information is kept.
Ensure that moving generic type information out of a comment doesn't cause type errors.

This would cause them to get lost when symex_target_equation merges ireps. This way we preserve the generic specialisation information.
