Subject Re: Help with Dependency Licensing
Date Tue, 11 Apr 2017 16:16:18 GMT
Please note that Cat X licenses are deemed to be incompatible with Apache
License, insofar that they are viral in nature, and FSF has made a claim
that dynamically linked languages, such as Java, forces the virality to the
dependent project... Meaning, if you have an import statement linking your
code to such dependency, there is legal uncertainty whether the entire
project must be under the copyleft license in question. FSF certainly
thinks so, and VP Legal has in the past concluded that we should have the
same stance.

So when is the optional Cat X dependency acceptable?

For instance, an acceptably licensed API specification is what our project
depend on, and some runtime mechanism (such as Java Service Loader or
Spring Dependency Injection) make that available. Without this indirection,
we ain't allowed to have dependency on Cat X for Java (and other
circumstances).
