I use the serializer v3.4.0 with Symfony 5 and just ran into the issue:

Notice: Accessing static property Symfony\Component\Cache\Adapter\PhpArrayAdapter::$valuesCache as non static

ErrorException in /vendor/jms/serializer/src/Accessor/DefaultAccessorStrategy.php (line 86)

                    $this->readAccessors[$metadata->class] = \Closure::bind(static function ($o, $name) {
-->                     return $o->$name;
                    }, null, $metadata->class);

Stack trace:

Looks like the serializer stumbled upon some huge backtrace of an exception and could not cope with it, so probably it's not an issue.

@goetas can you please release this functionality and update jms/serializer-bundle?
I really need this bugfix...
