You can't write a standalone Java application like this that makes use

org.eclipse.core.resources, require that the Eclipse platform be up and
running before you can do anything with them. I suggest rewriting the
code below as a plugin.

Actually, we can sue you. Even Google's cache contains the following

Official Eclipse 3.0 FAQs, published by
Addison-Wesley. No part of this

I am not a lawyer, just a book author, but if you copy text from a book at
verbatim and submit it to a newsgroup while removing the copyright you
violate the above restriction, I think.
Mmm, let's say there are 10,000 readers to this newsgroup. The book has 361
FAQs @ $36.
Multiple 10,000 readers by the cost of one FAQ @ $0.10 => $1,000.
I think we could ask you to send us a check for that amount, but I have to
check with my lawyer.

Please be advised that I consider my citation inappropriate
and I already removed (canceled) my newsgroup article with this citation.
Please notify me about any occurrences of my inappropriate post and I'll
do my best to destroy them.
Also I'll do my best to receive "prior consent of the publisher" in the
future. I regret that such consent can not be received in this case.
I truly believe that good will should be tried before any legal actions
and hope we're on the same page in this question.
PS. Google treats legal issues seriously. This faq is not in cache anymore.

Sincerely,

Hi Sam,
We were not planning on sueing you for this particular action, don't worry.
I just wanted to make a point. I appreciate your apology. Thanks.
Furthermore, I don't believe Google reacts to legal issues from two simple
book authors. They just update their cache when the original pages gets
updated by the prospective publisher, which is what we did. I scarcely think
Googles scans pages to see if they contain legal statements.
