Powermock is heavily relying on the internal workings of Mockito. As result hight cost of compatibility maintenance. We should move to using public SPI. Mockito team is ready to help and provide change in API.

Main goal: clean code without dirty hacks to get internals of Mockito.

We need:

• Identify using of Mockito internals and create a change request for Mockito
• Replace using internals of Mockito with using public API.
• Use delegate MockMaker to prevent issue with replacing Mockito MockMaker when PowerMock in class path (see PowerMockMaker with Mockito2 #769, Fixes #1003: Allow reloading of plugins. mockito/mockito#1004)
• Reporter - now internal, need ability to show custom message if mocking is failed for static methods
• Drop supporting Mockito 1.

• java.lang.IllegalAccessError: tried to access method org.mockito.internal.util.ObjectMethodsGuru.<init> #720 java.lang.IllegalAccessError: tried to access method org.mockito.internal.util.ObjectMethodsGuru.
