1[GitHub #806] DoThrowTest.shouldThrowCustomException() is failing2doThrow(new CustomException()).when(mockedList).add(anyString());3The test fails because PowerMockito is not able to mock the add() method of the ArrayList class. It throws a MockitoException:4The problem is that PowerMockito is not able to mock the final add() method of the ArrayList class. This is not a bug of PowerMockito but a limitation of Mockito. There is a workaround for this issue. You can use the following code instead:5doThrow(new CustomException()).when(mockedList, "add", anyString());6public static <T> T doThrow(Throwable toBeThrown, T mock, String methodName, Object... params) throws Exception7The doThrow() method is overloaded. This method is used to throw a custom exception on a method that is not mocked. The method is overloaded to accept the following parameters:8package samples.powermockito.junit4.bugs.github806;9import java.util.ArrayList;10import java.util.List;11import org.junit.Test;12import static org.junit.Assert.*;13import static org.mockito.Matchers.anyString;14import static org.powermock.api.mockito.PowerMockito.doThrow;15import static org.powermock.api.mockito.PowerMockito.mock;16public class DoThrowTest {17    public void shouldThrowCustomException() throws Exception {18        List<String> mockedList = mock(ArrayList.class);19        doThrow(new CustomException()).when(mockedList, "add", anyString());20        try {21            mockedList.add("one");22            fail("CustomException should
