In the note in
http://www.doctrine-project.org/docs/orm/2.0/en/reference/working-with-objects.html#merging-entities
It appears to state that private variables are not serialized for child objects

If this is the only reason entities can't have private properties, then this restriction is no longer valid, or possibly be reconsidered.

<?php

class A {
    private $a = null;

    public function setValue($value) {
        $this->a = $value;
    }
}

class B extends A {}

$b = new B();
$b->setValue("B");
var_dump($b);

$c = unserialize(serialize($b));
var_dump($c);

The output suggests private variables are serialized, and are restored fine

This totally correct behavior of PHP language. private variable are not visible for class that extend parent, if you want to see them you need to mark them as protected.

Indeed: https://3v4l.org/Ha3qj

Also, this was already fixed (we deal with merging private state, AFAIK).

Closing, unless somebody comes up with a failing test case.
