BC Break Report

Q	A
BC Break	yes
Version	3.17.*

Summary

As described in documentation PHP data type mixed should be possible map to JSON database type. After upgrading to 3.17.1 version this is not true anymore, and orm:schema-validate writes error because database json can now be mapped only to PHP array data type. Thus I lost posibility to use PHP mixed data type.

Previous behavior

Map PHP mixed data type to database JSON type.

Current behavior

ORM schema validation shows errors, because database JSON type can be mapped only to PHP array data type.

How to reproduce

#[ORM\Entity(SystemPropertyRepository::class)]
#[ORM\Table(schema: 'dw')]
class SystemProperty extends DataEntityWithKey
{
    /**
     * @var array value
     */
    #[ORM\Column(type: 'json')] //<-- this should be possible
    public mixed $value;
}
