Yes, but I think there is a misunderstanding here: the question is not what you ship together, but what is linked together.

If the judge asks you, if you can remove the JRE and Linux is still working (except for Java programs) you can say yes; if he asks you if you can put the JRE to a different Linux distribution and Java programs are still working, you can also answer "yes".

But if he asks you, if you can remove Mercurial  and the Mercurial Eclipse plugin is still working, the answer is clearly "No". The Plugin only works with Mercurial. Not with GIT, not with Bazaar. Insofar it is pretty hard linked. And that is imho a significant issue that makes the plugin derivative work.
