> In org.richfaces.application.InitializationListener.AWTInitializer, the initalize() method can fail to reset the context ClassLoader despite the finally block that should do that (from line 195):
> {code:title=org.richfaces.application.InitializationListener.AWTInitializer#195}
>             } finally {
>                 if (testStream != null) {
>                     try {
>                         testStream.close();
>                     } catch (IOException e) {
>                         LOGGER.error(e.getMessage(), e);
>                     }
>                 }
>                 thread.setContextClassLoader(initialTCCL);
>             }
> {code}
> In my OSGi environment, the testStream.close() invocation throws the NoClassDefFoundError pasted below.  This circumvents the subsequent intention to restore the context ClassLoader.  In effect, if AWT initialization fails the context ClassLoader is left in a bad state that prevents future ServiceTracker processing and hoses up the Faces initialization.
