Traits type annotations are not relative to the Trait filename

[EmilyShepherd]

Instead they use the filename of the class in which the trait is being used. For example:

src/Some/Directory/ExampleTrait.php:

namespace Some\Directory;

use My/Data/Type;

trait ExampleTrait
{
    /**
     * @param Type $type
     */
    public function testMethod(Type $type)
    {
        return null;
    }
}

src/Other/Directory/ExampleClass.php:

namespace Other\Directory;

class ExampleClass
{
    use ExampleTrait;
}

Using a ReflectionCompositeFactory on ExampleClass raises an Exception because \My\Data\Type is incompatible with \Other\Directory\Type.
