Description Mikolaj Izdebski 2014-03-30 16:14:47 EDT
Description of problem:
Despite the fact that license tag states "GPLv2+", parts of Azureus are licensed under GPL v2 only:
  grep "version 2 of the License only" `find -name *.java`

Azureus links with a number of GPLv2-incompatible components:
  apache-commons-cli (ASL 2.0)
  apache-commons-lang (ASL 2.0)
  eclipse-swt (EPL)
  log4j (ASL 2.0)
  junit (CPL, build-time only)
  json_simple (ASL 2.0)

Azureus also bundles some code under CPL (classes in org.pf).

Version-Release number of selected component (if applicable):
Comment 1 Sergio Monteiro Basto 2014-03-30 21:03:42 EDT
on https://sourceforge.net/projects/azureus/ 
License is GNU General Public License version 2.0 (GPLv2).

So drop the "+" fix this bug ? 
Linked to a number of GPLv2-incompatible components, but all in Fedora repos and one Common Public License also accepted by Fedora [1], what we need to do ? 

Comment 2 Mikolaj Izdebski 2014-03-31 02:49:50 EDT
The main problem is that the libraries azureus links with are all under GPLv2-incompatible licenses.  For example GPL code cannot be linked with EPL code.  Fedora licensing page you linked confirms that.  For more information, see:
Comment 3 David Juran 2014-04-07 02:39:01 EDT

Regarding the GPLv2+ tag, the '+' is probably a mistake on the behalf of the packager, for all I know, azureus is licensed for GPLv2 only, see http://wiki.vuze.com/w/Vuze_License.

Regarding linking with Eclipse SWT, The azureus project make an exception from the GPLv2 (also on http://wiki.vuze.com/w/Vuze_License) for this purpose. I don't claim I fully understand the details but would that make this linking acceptable and should the Licence tag then be "GPLv2 with exceptions"?

Regarding the rest, let me see what I can do...
Comment 4 Mikolaj Izdebski 2014-04-07 03:55:33 EDT
Thank you David for looking into this.

I agree with changing the license tag to "GPLv2" or "GPLv2 with exceptions".  In any case adding a comment to the spec file with the link to the wiki page would be nice.

The exception (if you can even call it this way) was to link with "EPL-licensed SWT" code only, but azureus also links with other components under EPL or CPL and with code under ASL 2.0 license, which is incompatible with GPLv2.
Comment 5 David Juran 2014-04-07 04:50:45 EDT
Yes, the EPL and CPL parts will need to be looked into/replaced. Reason I asked about SWT was that I don't think it's really feasible replacing this, so if the exception would not be sufficient, there would be little point putting effort into fixing the rest.
But I interpret #4 as SWT would be OK with the exception and I'll get started on the rest of the issues later during the week.

Comment 7 David Juran 2014-07-08 12:06:11 EDT
Mikolaj, regarding the ProgrammersFriend library, it seems it was LGPL at the time it was bundled into Vuze.
 Could you have a look at the discussion on http://forum.vuze.com/thread.jspa?threadID=122409 if you agree with what is said there?
Comment 8 Mikolaj Izdebski 2014-07-08 12:24:41 EDT
Azureus bundles verison ProgrammersFriend 2.0, which is dated July 26, 2003.  Judging from the web archive links it seems that older versions of ProgrammersFriend (before 2005) were indeed under LGPL (any verison), so that's not a problem from legal point of view as GPL code can be linked with LGPL.

The problem of bundled code *could* be justified by upstream license change - it is not possible to legally link azureus with latest PF, hence bundling.  But FPC still needs to revisit the case and grant an exception.

Of course the problem of linking with other libraries remains.

Discussion in upstream project about what their actual licence is ongoing in http://forum-archive.vuze.com/thread.jspa?threadID=122409

Comment 12 Fedora End Of Life 2017-07-25 14:38:50 EDT
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Comment 13 Fedora End Of Life 2017-08-08 07:45:51 EDT
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.
