I'm having trouble with richfaces 4.3.1 on weblogic 10.3.5.0, on deploy the following exception happens:
java.lang.RuntimeException: com.sun.faces.config.ConfigurationException: CONFIGURATION FAILED! duplicate key: class javax.faces.validator.LongRangeValidator

I had a look inside ClientServiceConfigParser and debugged it and I found that it ended up loading /META-INF/csv.xml twice from richfaces-components-ui-4.3.1.Final.jar
The method in question is:
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();
}
It seems something to do with Weblogic's ChangeAwareClassLoader (weblogic.utils.classloaders.ChangeAwareClassLoader). Because inside org.richfaces.javascript.ClientServiceConfigParser.parseConfig(String) when it runs ClassLoader loader = Thread.currentThread().getContextClassLoader(); it ends up returning the ChangeAwareClassLoader which happens to get 2 copies of the same resource. However if I null out the loader (using a debugger) so that it runs loader = ClientServiceConfigParser.class.getClassLoader();, then it ends up with a different classloader: weblogic.utils.classloaders.GenericClassLoader. Which doesn't get 2 copies of the same resource.
For what it's worth I'm using maven and have loaded in richfaces this way:
<dependency>
<groupId>org.richfaces.ui</groupId>
<artifactId>richfaces-components-ui</artifactId>
</dependency>
<dependency>
<groupId>org.richfaces.core</groupId>
<artifactId>richfaces-core-impl</artifactId>
</dependency>
Before people suggest that I've loaded the wrong maven depdencies, I can tell you its not related to: IllegalArgumentException: duplicate key (JSF)
Because using a debugger I confirmed that loader.getResources(name); returns the exact same resource.

Also for reference I tried the JSF forum and just put a post on the weblogic forums, but I figured I might get a better response here. The two other posts are here:

So aside from compiling my own version of rich faces, does anyone have any ideas of workarounds? How to disable the ChangeAwareClassLoader maybe? My Google searches haven't resulted in anything when trying to disable that class loader.
