problem with old jQuery version in wicket 6.16.0

hello,

I'm upgrading wicket from version 6.5.0 to version 6.16.0 (including
jQuery 1.11.1 now).
But I have to use jQuery 1.8.3, instead. I tried to achieve that with
following code in StartAplication#init.:

IJavaScriptLibrarySettings settings = getJavaScriptLibrarySettings();
settings.setJQueryReference(new
JQueryPluginResourceReference(Startseite.class, "query-1.8.3.min.js"));

Following RuntimeException is thrown:
org.apache.wicket.resource.CircularDependencyException: Circular
dependency detected in the dependency chain
[JavaScriptReferenceHeaderItem(scope:
org.apache.wicket.ajax.AbstractDefaultAjaxBehavior; name:
res/js/wicket-ajax-jquery-debug.js; locale: null; style: null;
variation: null, null), JavaScriptReferenceHeaderItem(scope:
org.apache.wicket.ajax.AbstractDefaultAjaxBehavior; name:
res/js/wicket-ajax-jquery.js; locale: null; style: null; variation:
null, null), JavaScriptReferenceHeaderItem(scope:
org.apache.wicket.ajax.AbstractDefaultAjaxBehavior; name:
res/js/wicket-event-jquery.js; locale: null; style: null; variation:
null, null), JavaScriptReferenceHeaderItem(scope:
de.khg.fundus.Startseite; name: jquery-1.8.3.min.js; locale: null;
style: null; variation: null, null)].
JavaScriptReferenceHeaderItem(scope: de.khg.fundus.Startseite; name:
jquery-1.8.3.min.js; locale: null; style: null; variation: null, null)
is already in the chain.

What's my mistake?

Thanks in advance
