java.lang.IncompatibleClassChangeError與嵌入式Jetty和澤西島（無GAE）

我正在創建一個基於Jersey + Spring +休眠的REST API。部署時一切正常。java.lang.IncompatibleClassChangeError與嵌入式Jetty和澤西島（無GAE）

我嘗試添加使用RestAssured一些集成測試，我想從一個嵌入式碼頭（強制性規範），但是它總是給這個錯誤啓動（見下文的詳細堆棧跟蹤）：

20-04-2013 | 19:14:43 | WARN | (Slf4jLog.java:76) | failed jersey-servlet: java.lang.IncompatibleClassChangeError: Implementing class 
20-04-2013 | 19:14:43 | WARN | (Slf4jLog.java:76) | failed [email protected]{/test-core,src/main/webapp}: java.lang.IncompatibleClassChangeError: Implementing class 
20-04-2013 | 19:14:43 | ERROR | (Slf4jLog.java:87) | Error starting handlers

由於該錯誤說這可能是我的SpringServlet，但我似乎無法解決這個問題。

和類的最終方法（類WithJetty是獲取擴展一個JUnit測試）將啓動我的碼頭服務器：

@BeforeClass 
public static void startJetty() throws Exception { 
    server = new Server(8070); 

    WebAppContext context = new WebAppContext(); 
    context.setDescriptor("src/main/webapp/WEB-INF/web.xml"); 
    context.setWar("src/main/webapp"); 
    context.setParentLoaderPriority(true); 
    context.setContextPath("/testing-core"); 

    server.setHandler(context); 
    server.setStopAtShutdown(true); 
    server.start(); 
}

的實際工作中的測試用例是很基本的：

public class UserResourceTest extends WithJetty { 
    @Test 
    public void test() throws Exception { 
     Assert.assertEquals(200, given().log().all().get(RSConstants.PATH_UNSECURED + "/test").getStatusCode()); 
    } 
}

我已經走遍了互聯網和StackOverflow上可行的解決方案，但他們都我發現有一些東西與GAE（我不使用）

非常感謝您的幫助！

我確信我的開發JDK是java 7，可惜問題依然存在。 – Sem 2013-04-26 13:23:10

我試圖從1.7.2升級到1.8.0或更新版本時遇到同樣的問題。所以我建議降級到1.7.2作爲解決方法，直到提供更好的解決方案。
