The method ReflectionMethod::setAccessible doesn't change the accessibility of a private method defined in a trait.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at and the instructions on how to report
a bug at

Hi, your last line has the mistake.

Try '$method->invoke($bar);' instead, and at least on my machine it works.

The reflection mirror knows about your change, the original class is left 
unchanged. And, as with normal classes, you need to use the mirror and invoke() 
to bypass visibility.

Please reopen if I misunderstood something!
