Request for comments: OpenJDK Trademark Notice

Over the last couple of months a group of us here at Sun has been working
with developers at Red Hat and Canonical to integrate packages based on
the open-source JDK 6 code  into the upcoming Fedora 9  and Ubuntu
Hardy Heron  releases.
The names of these packages include the token "openjdk", and the version
strings say "OpenJDK". In Hardy Heron, for example, the packages share
the prefix "openjdk-6", and running "java -version" after installing them
produces the output:
openjdk version "1.6.0"
OpenJDK Runtime Environment (build 1.6.0-b06)
OpenJDK Server VM (build 1.6.0-b06, mixed mode)
Now "OpenJDK" is a trademark of Sun Microsystems, so we had to come up
with a way to grant permission for these types of uses. Working with
Sun's trademark counsel we drafted the OpenJDK Trademark Notice and
published the first version in the b06 source bundle, in the TRADEMARK
file at the root of the tree. Based on early feedback from Andrew Haley,
Dalibor Topic, Mark Wielaard, and others, we revised it slightly and
published v1.1  in b07, which shipped yesterday .
We couldn't address all of the open issues in time for v1.1, so attached
below is the current draft of version 1.2 of the Notice. The differences
from v1.1 are:
- The term "Owner" has been changed to "Trademark Owner", just to
make it absolutely clear that Sun is not, in this Notice, claiming
ownership of anything other than the "OpenJDK" trademark;
- The list of URLs from which the original code may be downloaded
has been corrected and clarified, and also generalized to allow
successor locations to be designated in the future;
- A clause has been added to allow porting efforts to use the
- A clause has been added to allow downstream repackagers to use
the HotSpot code from a different source tree if necessary, e.g.
in order to use the C++ interpreter that's available in the jdk7
tree but not in the jdk6 tree.
We hope to finalize this new version of the Notice by the end of next
week (28 March). Comment and suggestions are most welcome.

development-kit or runtime-environment source code retrieved from a single
Website, and the vast majority of the Software code is identical to that
upstream Original Software, except that:
(a) Changes required to port Original Software to new operating systems
or hardware architectures are permitted, so long as that work takes
place in the context of an approved Project hosted in the OpenJDK
(b) A Virtual Machine from one Website may be combined with the Library
and Tools of another Website, so long as the vast majority of the
code in each is identical to the corresponding upstream Virtual
Machine or Library and Tools component.
