There was a problem hiding this comment.
callback->CreationContext() seems a little more correct than recv->CreationContext() because the former is the context the actual callback takes place in but it's admittedly a mostly academic difference.

Check that invoking a callback on a receiver from a different context works. It ran afoul of an `env->context() == isolate->GetCurrentContext()` assertion so retrieve the environment from the callback context and the context to enter from the environment's context() method. We could also have retrieved the environment from the receiver's context and that would have made little practical difference. It just seemed more correct to get it from the callback context because that is the actual execution context. PR-URL: nodejs#9221 Reviewed-By: Anna Henningsen <anna@addaleax.net>
