 Hi,

 quite unfriendly on this regard.

I think that the LGPL v3 is compatible with the EPL.  The LGPL allows
you to convey combined works as long as you can recompile the LGPL
parts.  Since we have the source for everything, this is not a
problem.

 Any advice on the matter will be highly appreciated.

Dear Pablo,

It looks like Aelitis/Vuze is the copyright owner of most of the GPL'ed code,
so the quickest way to solve the problem may be to ask them to add a license
exception to allow combining their code with the co-distributed EPL and
CPL-licensed sources. I hope others will correct me if I am wrong, but it seems
that the CPL does not forbid the program to be linked with works under other
licenses, so exception is only needed on the GPL side.

According to debian/copyright, this leaves two files to either replace or get
relicensed by their authors:

Files: com/aelitis/azureus/core/peermanager/utils/BTPeerIDByteDecoder.java
Copyright: 2003-2006, Aelitis
   2002-2004, Alon Rohter
License: GPL-2+

Files: org/gudy/azureus2/core3/util/BrokenMd5Hasher.java
Copyright: 2005, jMuleGroup
License: GPL-2

Have a nice day,
