 Maybe this is of any interest from catalina.out on 7.0.19 with NIO.

 Long before the first exception about a recylced response facade I get this:
 Aug 15, 2011 10:55:07 AM org.apache.tomcat.util.net.NioEndpoint processSocket
 SEVERE: Error allocating socket processor
 java.lang.NullPointerException

 And some similar NPE's and a day later I get this:

 If I try the first failing request again. It doesn't fail. So it is not as easy as repeating
a request. I haven't checked if this request uses ImageIO yet.
