#1026 CDK may be violating the Jumbo Artistic License

[Egon Willighagen]

One of the clauses discussing exposing of the interface, which the CDK is certainly doing. Being Java, I see no way of restricting access to the Jumbo API:

(8) You are permitted to link Modified and Standard Versions with
other works, to embed the Package in a larger work of your own, or
to build stand-alone binary or bytecode versions of applications that
include the Package, and Distribute the result without restriction,
provided the result does not expose a direct interface to the Package.

Clarification must be sought with the Jumbo authors.

That's "Artistic License 2.0", and one solution might be to relicense JUMBO under provision of section 4(c)(ii).

Discussed with upstream. It is not considered a problem.
