No foreign key in sqlite

[fmathieu1]

Bug Report

Q	A
BC Break	Yes
Version	>=2.6.5

Summary

Since I upgraded doctrine/orm to 2.6.5 from 2.6.3 I no longer have foreign keys on my SQLite.
I tried version 2.6.4 and it works as expected.

Current behavior

I can no longer use onDelete="CASCADE" and such

How to reproduce

Given my Category entity, referencing itself as parent

class Category 
{
    /**
     * @var Category|null
     *
     * @ORM\ManyToOne(targetEntity="Category")
     * @ORM\JoinColumns({
     *     @ORM\JoinColumn(name="parent_id", referencedColumnName="id", nullable=true, onDelete="CASCADE")
     * })
     */
    private $parent;

}

Expected behavior

i can use onDelete="CASCADE" to have children removed when a parent is removed

We are running into the same issue on one of our projects where we use the SQLite platform in our test environment because it's easier to bootstrap than e.g. MySQL.

The issue appears to be caused by this change: #7842
