Rhino is available under the MPL/GPL dual license, so should be GPL
compatible. And GPL+Exception should be compatible with MPL (if the MPL
part is kept as a separate module). If that isn't enough for some
people, we could see whether upstream wants Rhino to upgrade to MPLv2
(which would add all secondary MPLv2 licenses too, so LGPL and AGPL dual
licenses next to the current MPL/GPL) [*].

I talked to Luis Villa and Gervase Markham about a possible upgrade and
the implications. They have both worked on MPLv2 and were very
supportive (but of course it will be up to the actual upstream Rhino
developers to decide whether or not to upgrade).

I think it would be really beneficial to make upstream, ClosedJDK,
OpenJDK and IcedTea share the exact same version of Rhino. Currently
IcedTea uses the (latest) upstream version available, but that might
lead to subtle incompatibilities.

But I couldn't find the actual Rhino source code used in ClosedJDK.
Where is that currently available?

Making sure all our work on Rhino, whether it is for ClosedJDK, OpenJDK,
IcedTea, or the bsd/macosx-port is done upstream seems like a good idea
in general.

Thanks,

Mark
