To note, for Mockito-6, there are two bugs revealed:

  1. Simulator Debugging result changed from "found root cause" to "over_skip". correct rev. 098ed5f0b3546a8eba1c95c7b7a5a8df53fc04e6 [098ed5f] buggy rev. b44c72a57739ada4e8966a9b510a76828158ccc0 [b44c72a]
  2. Agent crash with "java.lang.reflect.Method" added in "includes" option to be instrumented. (hidden bug reveals)
