Sean Owen commented on SPARK-5669:
----------------------------------
I do find it confusing. I can see an argument that this is allowed on the
grounds that it *does* meet the exception because the target work is created
*without* GCC, and on the grounds that it is *not* a Category X license case as
described in http://www.apache.org/legal/resolved.html#category-x , even though
the list calls out "special exception to the GPL" licenses, since the problem
it identifies regarding derived works is *not* part of the exception terms.
If that's true, I don't even see that a notice is required.
On that grounds, you could put back the binaries into 1.3. (Yes, it's a moot
point in 1.4). Your reasoning is that it would prevent users from having to
bring their own JBLAS if they already use JBLAS. But they'll have to in 1.4
anyway, and we've always required programs to bring their own dependencies even
if they're also used by Spark. I suppose I'd favor taking that hit earlier than
later, since it happens anyway, and if it lets us be a tiny bit more
conservative about the licensing issue.
But I do not feel strongly about it. Having said all that, would you rather
proceed with just putting back the libs in 1.3?

> Unfortunately the libgfortran and libgcc libraries included for Windows are
> not licensed in a way that's compatible with Spark and the AL2 -- LGPL at
> least.
> It's easy to exclude them. I'm not clear what it does to running on Windows;
> I assume it can still work but the libs would have to be made available
> locally and put on the shared library path manually. I don't think there's a
> package manager as in Linux that would make it easily available. I'm not able
> to test on Windows.
> If it doesn't work, the follow-up question is whether that means JBLAS has to
> be removed on the double, or treated as a known issue for 1.3.0.
