When I try to use PowerMockito (the latest available 1.6.5) alongside Mockito 2.1.0 I get an exception in every test run even if tests do not use PowerMockito.

java.lang.AbstractMethodError: org.powermock.api.mockito.internal.mockmaker.PowerMockMaker.isTypeMockable(Ljava/lang/Class;)Lorg/mockito/plugins/MockMaker$TypeMockability;

This issue has been post to Mockito's github and it is clear PowerMockito has not adopted the latest Mockito changed yet.
mockito/mockito#292

The same issue is asked at StackOverflow:

Observed behavior: AbstractMethodError
Desired behavior: no error
