Symfony version(s) affected

6.2.4

Description

When an exception is thrown in debug mode in the callback passed to Symfony\Contracts\Cache\CacheInterface::get(string $key, callable $callback), Symfony will end up masking the exception with its own as CacheDataCollector throws the following exception:

Typed property Symfony\Component\Cache\Adapter\TraceableAdapterEvent::$end must not be accessed before initialization in symfony\cache\DataCollector\CacheDataCollector.php on line 118.

How to reproduce

Probably something like the following should get it to trigger, although in my testing, it does not.

$cache->get(
    'foo',
    function (ItemInterface $item) {
        throw new \Exception;
    }
);

I am not sure what it is about my app in particular that triggers it, but the exception is actually thrown from a fiber, in case that matters. Here's a snapshot of $calls.

Possible Solution

No response

Additional Context

This does not happen on Symfony 5.4; the correct userland exception message and trace is shown, instead of one coming from Symfony's components.
