1) This is permitted, though it turns the complete package into GPL.
This is also why libcdio has moved from gst-plugins-good to
gst-plugins-ugly. Note that LGPL gives permission to change the license
to ordinary GPL in section 3.

2) I found some bugreport on launchpad with that claim from you, but
besides that, I can't find any information. The bugreport says you
should take it up with the FSF, but somehow I can't find any reference
about that.

If linking GPL and CDDL code together isn't a problem for you and your
lawyers, then I don't know why 1) would be a problem for you either.

As for your claims, there's still an open question for you:
