The private methods and properties of a trait in `/vendor/` do not cached

[ging-dev]

<?php
class A {
    use BTrait; // BTrait on somewhere in /vendor/

    public function test() {
        $this->privateMethod(); // Call to unknown method, privateMethod() from BTrait.
    }
}

Maybe issue with private constant, i guess
