Jira issue originally created by user digitalkaoz:

Currently its not possible to use Collection with Array-Types transparently:

class Entity
{
    /****
     * @var string[]|Collection
     *
     * @ORM\Column(type="json_array")
     */
    private $aliases = [];

    public function **construct()
    {
        $this->aliases  = new ArrayCollection();
    }
}

if i add Values to the Collection and persist the Entity the aliases are empty.
I need Lifecycle Listener which converts between ArrayCollection and array like this:

    /****
     * @ORM\PrePersist
     */
    public function prePersist()
    {
        $this->aliases = $this->aliases->toArray();
    }

it would be good to have an automatic conversion! Should be fairly easy, i could write a PR if your interessted in...or am i missing a hidden piece?
