powermock在线程中遇到异常；“主要”；java.lang.ExceptionInInitializeError

我正在使用JUnit4.12、mockito 1.10.9和powermock 1.6.6 同样的版本组合在其他项目中的其他地方也适用

我遇到了一个例外。。 线程“main”java.lang.ExceptionInInitializeError中出现异常 位于org.mockito.internal.exceptions.stacktrace.ConditionalStackTraceFilter

import static org.mockito.Mockito.mock;

@RunWith(PowerMockRunner.class)
@PrepareForTest(OfsClientUtilities.class)
public class deleteme {

@Test
public void getAverageTest() throws IOException {
    Client client = mock(Client.class);
    Invocation.Builder target = mock(Invocation.Builder.class);
    Response response = mock(Response.class);

    PowerMockito.mockStatic(OfsClientUtilities.class);

    Mockito.when(OfsClientUtilities.getOfsRestClient(any(), anyString(), 
    anyString())).thenReturn(target);

    Mockito.when(target.get()).thenReturn(response);
    Mockito.when(response.getStatus()).thenReturn(HttpStatus.SC_OK);

    String jsonString = deleteme.read("somefile.json");

    Mockito.when(response.readEntity(String.class)).thenReturn(jsonString);
....}
