PowerMock @SuppressStaticInitialization fixed the issue.

Note: You must not pass the class name but a fully qualified name of class in parameter of @SuppressStaticInitialization

e.g. 

@RunWith(PowerMockRunner.class)
@PrepareForTest({staticClassExample.class}
@SuppressStaticInitialization("com.services.ClassWithStaticBlockInitialization")
public class ClassNameTest {
...
}
