Andreas Lehmkühler commented on PDFBOX-3906:
--------------------------------------------
[~hennejg] Those assumptions are not correct.
Copied from the [ASF release
policy|http://www.apache.org/legal/release-policy.html]
{quote}
Every ASF release MUST contain one or more source packages, which MUST be
sufficient for a user to build and test the release provided they have access
to the appropriate platform and tools.
{quote}
Therefore those binary test files have to have a [suitable
license|http://www.apache.org/legal/resolved].
- public domain shouldn't be a problem
- a non-commercial restriction is problematic
- files with an unknown license like the dithered photo or the page from the
CCITT specification are problematic
I've searched the archives and found a lot discussions about that. In most
cases the files in question must not be included. There are some rare cases
with some very special exceptions.
We can try to get an exception for some of the files, but I'm afraid we won't
get them for all of them. An alternative is to host the problematic test files
some where else and download them while building the plugin. Or do I miss
something?
