Messenger does not throw a MessageDecodingFailedException for some messages that have invalid bodies when using the native PHP serialize/deserialize format.
This happens because unserializing an empty string does not issue a PHP warning, and simply returns false.

Hey!

I see that this is your first PR. That is great! Welcome!

Symfony has a contribution guide which I suggest you to read.

In short:

  • Always add tests
  • Keep backward compatibility (see https://symfony.com/bc).
  • Bug fixes must be submitted against the lowest maintained branch where they apply (see https://symfony.com/releases)
  • Features and deprecations must be submitted against the 5.4 branch.

Review the GitHub status checks of your pull request and try to solve the reported issues. If some tests are failing, try to see if they are failing because of this change.

When two Symfony core team members approve this change, it will be merged and you will become an official Symfony contributor!
If this PR is merged in a lower version branch, it will be merged up to all maintained branches within a few days.

I am going to sit back now and wait for the reviews.

Cheers!

Carsonbot

Fixed the code style and added a test, but not sure its naming is the best

Ensure a MessageDecodingFailedException is thrown when the string to be unserialized is an empty string.

This happens because unserializing an empty string does not issue a PHP warning, and simply returns false.
