The strange thing is that at line 181
https://github.com/apache/wicket/blob/build/wicket-6.1.1/wicket-core/src/main/java/org/apache/wicket/protocol/http/servlet/ServletWebResponse.java#L181

But at WicketFilter.processRequest(WicketFilter.java:198) the
RequestCycle threal local must be still available.
