ExceptionInInitializerError with PowerMock and Robolectric - eclipse

Question

I want to use Robolectric with PowerMock, but I'm having some trouble getting them to run. I think it's a dependency issue -- right now my jars are just managed in Eclipse.
I'm getting an ExceptionInInitializerError in two ways. The first is this:
#RunWith(RobolectricTestRunner.class)
#PrepareForTest(Logger.class)
public class Logger_Test {
#Mock Config config;
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
}
Fails with :

It works fine with PowerMockRunner, but throws the same exception with it as a Rule.
#PrepareForTest(Logger.class)
public class Logger_Test {
#Rule public PowerMockRule rule = new PowerMockRule();
#Mock Config config;
#Before
public void setUp() {
MockitoAnnotations.initMocks(this);
}

Answer 1

Add #PowerMockIgnore({ "org.mockito.*", "org.robolectric.*", "android.*" }) as the doc: https://github.com/robolectric/robolectric/wiki/Using-PowerMock

Answer 2

In place of #RunWith(RobolectricTestRunner.class) use #RunWith(PowerMockRunner.class)
