The funny irony here is that the current arrangement you list below was
JDK7 b23 as part of the open sourcing plan (although nashorn came in
we also switched from SCCS+teamware to mercurial.
The last build before that - JDK 7 b22 - had just hotspot+j2se as you
plus a "top-level" repo - (if you ignore the closed repos for the plugin
So what goes around comes around ... but I wonder if anyone remembers
and advocacy behind splitting it in the first before we spring back to
how it was before ?
I could probably dig up some old internal emails but not quickly.
