I have created my own reference and added this inside getDependencies method:
List dependencies = new ArrayList<>();
dependencies.add( CssHeaderItem.forReference(
BootstrapCssReference.instance() ) );
return dependencies;
and it works.
Thanks for advice.

Hi,
Override ResourceReference#getDependencies() for the reference that
contribute bootstrap-override.css.
It should depend on
CssHeaderItem.forRefernce(de.agilecoders.wicket.core.markup.html.themes.bootstrap.BootstrapCssReference)
See http://wicketinaction.com/2012/07/wicket-6-resource-management
