This changeset improves PHP 8.6+ support by avoiding the deprecated spl_object_hash() function in tests. The suggested spl_object_id() requires PHP 7.2+, so the test now compares the container instance directly to keep supporting PHP 7.1. With these changes applied, tests against the current PHP 8.6 RC pass without errors.
