FAQ #24 of the eplfaq says that if your question isn't answered there,
to contact license@eclipse.org.
I think that your question is:
"If I modify Eclipse code and compile the modified code, can I use the
resulting object code in a commercial program redistributed in object
form only?"
(If I'm incorrect, please clarify further).
The eplfaq has question #15 that says "Can I take a Program licensed
under the EPL, compile it without modification, and commercially license
the result?"
If I'm correct about your question, it is a question like "Can I take a
Program licensed under the EPL, modify it, compile it, and commercially
license the result?"

Hi Lee
your interpretation of my post

> Program licensed under the EPL, modify it, compile it, and commercially
> license the result?"
is not exactly what I meant. I was essentially asking if you can
take "code snippets" (lines/methods/classes) of an EPL program,
possibly modfy them to suit your program, and use them in you own
commercially licensed, distributed in object code form only, without
having to distribute your sources (the ones where you have made use of
some code coming from an EPL-licensed program).

Well, you're asking for an opinion about a legal document (the EPL) and
applicable copyright law, so it certainly sounds like legal advice to
me. If there's an economic/legal risk, you should ask your lawyer. If
there's no risk, flip a coin.
Here's my non-lawyer opinion about your question...

The FAQ isn't the controlling document, the license (EPL) is. The
license says that sources for any derivative works created from EPL code
must be distributed.
You could claim a "fair use" exception if the "snippets" are small
enough, but that's a very gray area and the courts weight a whole bunch
of factors like total size, % of overall work, use, economic impact,
etc, etc. You might have seen guidelines from various projects that say
anything more than NN lines of code requires a contributors agreement
and you could try to pick a number out of the air like that as well, but
it's really not that simple.
Your followup gives examples of "snippets" (some of which are pretty
non-snippety to may way of thinking), so here's my gut reaction to them:
- Class - definitely not fair use
- Method - probably not fair use unless its a small/trivial method
- Lines - probably fair use as long as it's not too many lines (whatever
"too many" means)

Edoardo,
If you copy any EPL code *and *make changes to that copy, those changes
need to be made available under EPL-license in source form. That
doesn't mean the whole product built around it can't be commercially
licensed closed source, it just means you must share the source. I know
of IBM products that do this kind of copy it and change it type of thing
with EMF/SDO, and then make a zip file of just the changed files
available on some public website when the product is shipped...
