Sean Owen commented on SPARK-5669:
----------------------------------
It *should* be fine on the grounds that the native libs are on the classpath
and there is no conflict. That said I have not tried it. Are you proposing the
new PR for 1.3.0? That would also solve the issue. If not, I would support it
if you felt more comfortable restoring the native libs for 1.3.0 instead.

> 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.
