crawler4j: Problems with "?" in robots.txt

In https://www.welt.de/robots.txt there are ? containing entries like Disallow: /*?config. Hence https://www.welt.de/test?config should be allowed but it is not. Whereas entries like Disallow: /*.xmli work properly and disallow https://www.welt.de/test.xmli. After my investigation I figured out that ? is the problematic character.

I use RobotstxtServer#allow("https://www.welt.de/test?config") for testing.
