Subject Re: LGPL dependency
Date Fri, 14 Jun 2019 08:03:38 GMT

In the link your shared, there is this
> For example, if you distribute copies of the library, whether gratis or for a fee, you
must give the recipients all the rights that we gave you. You must make sure that they, too,
receive or can get the source code. 

This is not compatible with our Apache 2.0 and Apache public good goal. Apache software should
allow all users to use as their wish, even don’t open source again, sell the fork/mutation
versions as they will.

LGPL has been discussed many times, but that is not the only concern here.

If that possible, week don’t depend on this in runtime? Dynamic links are same as Java dependency,
which should not be allowed.

This is my personal perspective only.
