10.3.5.0重複鍵，上部署以下例外情況：RichFaces的4.3.1的WebLogic上我在WebLogic上的10.3.5.0與RichFaces的4.3.1麻煩部署

我裏面看看ClientServiceConfigParser和調試它，我發現，它結束了裝載/META-INF/csv.xml從兩次RichFaces的組件-UI-4.3.1.Final.jar
問題的方法是：
public static Map<Class<?>, LibraryFunction> parseConfig(String name) {
ClassLoader loader = Thread.currentThread().getContextClassLoader();
if (null == loader) {
loader = ClientServiceConfigParser.class.getClassLoader();
}
Builder<Class<?>, LibraryFunction> resultBuilder = ImmutableMap.builder();
try {
Enumeration<URL> resources = loader.getResources(name);
while (resources.hasMoreElements()) {
URL url = (URL) resources.nextElement();
resultBuilder.putAll(parse(loader, url));
}
} catch (IOException e) {
return Collections.emptyMap();
}
return resultBuilder.build();
}
I t似乎與Weblogic的ChangeAwareClassLoader（weblogic.utils.classloaders.ChangeAwareClassLoader）有關。因爲在org.richfaces.javascript.ClientServiceConfigParser.parseConfig(String)裏面，當它運行ClassLoader loader = Thread.currentThread().getContextClassLoader();時，它最終返回ChangeAwareClassLoader，恰好得到相同資源的2個副本。但是，如果我將加載程序清零（使用調試程序）以使其運行loader = ClientServiceConfigParser.class.getClassLoader();，那麼它最終會得到一個不同的類加載程序：weblogic.utils.classloaders.GenericClassLoader。其中沒有獲得相同資源的2份副本。
對於什麼是值得我使用maven和RichFaces的已加載這樣：
<dependency>
<groupId>org.richfaces.ui</groupId>
<artifactId>richfaces-components-ui</artifactId>
</dependency>
<dependency>
<groupId>org.richfaces.core</groupId>
<artifactId>richfaces-core-impl</artifactId>
</dependency>
以前人們認爲我已經加載了錯誤的行家depdencies，我可以告訴你，它不涉及到： IllegalArgumentException: duplicate key (JSF)
由於使用調試器，我確認loader.getResources(name);返回完全相同的資源。

也可對照我嘗試了JSF論壇，只是把weblogic的論壇帖子，但我想我會在這裏得到更好的反應。兩個其他職位在這裏：

所以從編譯我自己豐富的面部的版本之外，沒有任何人有解決方法的任何想法？如何禁用ChangeAwareClassLoader也許？嘗試禁用該類加載器時，我的Google搜索沒有產生任何結果。
