Is Sun Evil?

At least this is not kind:

Hi all,

Yesterday our institution, the University of Tübingen, Germany, received
an email from SUN. The email started by saying that SUN is pleased to
see projects written in their programing language "Java" that we provide
at our institution. However, they wanted us to rename our Evoulutionary
Algorithms package "JavaEvA" to something like "JEvA" and our Neural
Network project "JavaNNS" should also be renamed to something else like
"JNNS". The reason for this is that SUN owns a trademark on the name
"Java" and no other institution or company is supposed to use this name
for its own purposes or software packages, even if this is a non profit
and/or open source project as JavaEvA and JavaNNS. We might later even
get a dissuasion letter if we do not follow the instructions in the email.
I do not exactly know how SUN and the BioJava project are connected.
However, in the worst case someday we could also receive a writing like
that.
To summarize: we should be aware that possibly the name "BioJava" has to
be changed to something else like "JBio" or "BioJ" or what ever SUN
might suggest as soon as they recognize our project. If there is already
an agreement with SUN about that, I am not well informed and curious to
know about it. Otherwise you are now informed about what happened to us
in Tübingen.

Sincerely,
Andreas Dräger

So, to summarize: You, we, nobody is allowed to use the name "Java" for a "software product" like BioJava. Btw: Didn't Sun planned to release Java into the Open Source community?
