illegal reflective access operation: AccessibilityChanger

Hi.

I’m using IntelliJ Community 2017.3 and when I run junit tests using “Menu>Run>Run All In Owner” in my project (https://github.com/lviggiano/owner/) I get the following warning at the console:

I cannot identify the problematic test, since I have hundreds and this happens when I run them all at once. But eventually if I find the problematic one, I’ll update this issue.

I’m using mockito-core 2.15.0; java 9.0.1, Maven 3.3.9, Mac OS X 10.13.3

Hi,

Found another similar issue running OpenJDK 11:

In my case, changing the dependency from mockito-all:2.0.2-beta to mockito-core:3.2.4 solved the problem
