…rrabus)This PR was merged into the 4.3 branch.Discussion----------Allow WrappedListener to describe uncallable listeners| Q | A| ------------- | ---| Branch? | 4.3| Bug fix? | yes| New feature? | no| BC breaks? | no| Deprecations? | no| Tests pass? | yes| Fixed tickets |#31493| License | MIT| Doc PR | N/AThis is a follow-up to#31493. The previous PR did not fix the problem completely. We also need to make sure that a listener that is not callable is not passed to `Closure::fromCallable()`.Note: It would probably be a good idea to give the developer a hint about uncallable listeners. Currently, such a listener causes an exception at the worst possible point of time: when collecting the profile information. This breaks the toolbar without any helpful feedback, as I've described [here](#31493 (comment)).This PR allows the `WrappedListener` class to describe a listener for the profiler even if the listener is not callable, which was the behavior in Symfony 4.2.Commits-------bc3f598 Allow WrappedListener to describe uncallable listeners.
