NPG: when?

[Apologies for abusing an existing thread :-/ I changed the subject line]

Is there an answer? Or was it a slow osmotic drift towards NPG, so no
clear boundary can be defined?

In that case, the question might be modified to: in which JDK/HSX
release was the former Perm Gen removed from the JVM? If no one
recalls, I'll commence some archeology, pick-axe and all.

A related hsx mercurial question: I see tags for hsx versions/builds
such as hs23-b02 or hs24-b04 (for example), but none for the "dot"
releases such as "hs23.5-b02" or "hs24.2-b06". Are those dot tags not
possible because the dot releases are branches off of the non-dot
parent along with cherry-picked cangesets from the main trunk, or in
addition to those in the main trunk? I suppose there are no public hsx
"dot" repos, right?
