Tries to set URL.setURLStreamHandlerFactory() with the provided factory. If it fails, it tries to reset handler by creating a BridgeHandlerFactory and hacking the JDK to overcome URL.setURLStreamHandlerFactory()'s limitation of only being able to be set up once. If there is already an existing handler factory then this factory will be added to the bridge list
