Mockito 2.1.0 throws IllegalAccessException

[delverdev]

I updated Mockito in my project to 2.1.0 and now all tests that use @SpyBean fail with the following StackTrace:

java.lang.IllegalAccessError: tried to access method org.mockito.internal.util.MockUtil.()V from class org.springframework.boot.test.mock.mockito.SpyDefinition

I also created an example that represents the error.

Compatibility with Mockito 2 is available as of Spring Boot 1.5 (see #6520)
