Yes, it's horrible. Given the way the old HTTP/1.1 connector is written it's
very hard and very risky to fix :-(
Use Coyote instead for deperate situations ;-)
At least, one version which doesn't throw a NPE (I suppose it does help).
I tried the example you mentioned above and your "nasty" 302 AvantGo
servlet, and both work fine in 4.1.1 (and 4.1.0 probably).
