I think the confusion between LGPL and Java is obviously a
misunderstanding that will blow over shortly if it hasn't already.
Clearly, the LGPL was supposed to allow library-like linking.
These are the best discussions I found on the subject:
Professor Eben Moglen who often works for FSF, had this to say:
"2) Clarifying the GPL
One issue that I know has come up for me is how the GPL applies in
situations where I'm using GPL software but I'm not actually modifying
it. For example, I write a Java application, and it is reliant on a JAR
that is GPL'd. Do I then need to GPL my software? I haven't changed the
JAR in anyway, I'm just redistributing it with my software. The end user
could just as easily download the JAR themselves, it's just a
convenience for me to offer it in my package.
The language or programming paradigm in use doesn't determine the rules
of compliance, nor does whether the GPL'd code has been modified. The
situation is no different than the one where your code depends on static
or dynamic linking of a GPL'd library, say GNU readline. Your code, in
order to operate, must be combined with the GPL'd code, forming a new
combined work, which under GPL section 2(b) must be distributed under
the terms of the GPL and only the GPL. If the author of the other code
had chosen to release his JAR under the Lesser GPL, your contribution to
the combined work could be released under any license of your choosing,
but by releasing under GPL he or she chose to invoke the principle of
"share and share alike.""
