Yes somehow It worked in 7.x
Based on the suggestions from you all, In 9.x, I use custom
IHeaderResponseDecorator
for Css resources to load into the header section, it works.
And JavaScriptFilteredIntoFooterHeaderResponse is used with a
wicket-container bucket for JS resources to load into the footer before end
of body, but it loads into header section which is not expected.
