It is forest. Closed repos are created on side on different file server and not related to open part in any way (in 
Mercurial sense). And it is the same setup as in our Hotspot sources.
When we need to push related changes (for example, change method signature) into open and close repos we create separate 
changesets in those repos but with the same changeset header/descriptor, at least with the same bugid:synopsis and 
summary:description lines (in ppc-aix project we will get different authors and reviewers).
To prepare for testing we pull them together in one place. Closed repos are cloned as sub-directories of open sources: 
hotspot/src/closed, hotspot/make/closed and hotspot/test/closed. So from build system view it is one source with top 
/hotspot/ directory.
We have to test and push such changes together since they are related. That is why we asked permission to push into open 
part of this project.

Note: our testing system JPRT keeps builds from push job for long time (years) so later, when some more complex testing 
finds a problem, we can track which push/changes introduced the regression. It helps diagnose the problem.
I want to use JPRT to push all changes which modify shared sources and may affect our closed parts.

Yes, it is my main motivation. It is faster to deal with one conflict at time than allocate resources later to fix 100s 
conflicts. This way we will be more confident about these changes when we will make decision to push it onto main branch.
