Eclipse no longer working with 1.9.0-ea-b61

[Andreas Kohn]

Eclipse no longer starts with 1.9.0-ea-b61 or higher, complaining about
missing org.w3c.dom.stylesheets.StyleSheetList.

I'm guessing this is due to
http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8042244 (Re-examine the
supportedness of non-SE org.w3c.dom.** API), which points to a regression
that should be fixed with
http://bugs.java.com/bugdatabase/view_bug.do?bug_id=8078139
Unfortunately doing a local build from 9dev with the commit for that bug
included doesn't help, the message stays the same.

Is this an eclipse issue, or a legitimate regression on the JDK side?
