Indeed, Eclipse seems to load them from a javax.xml bundle as well,
attached are the -verbose and -verbose + -Dsun.misc.URLClassPath.debug logs.

Quick grep:
[andreas at winterfell ~]$ grep org.w3c.dom.stylesheets
eclipse-9-internal-app-verbose-debug.out
URLClassPath.getResource("org/w3c/dom/stylesheets/DocumentStyle.class")
[Loaded org.w3c.dom.stylesheets.DocumentStyle from
