License clarification

Hi,
We try to import your customized release...
there is a bit of confusion regarding the license of this library
in https://code.google.com/p/jj2000/ is reported as LGPLv2
in the pom file is used jj2000 License (master).
For Fedora we have a problem for import this library.
For two reasons, jj2000 :

  1. The license it is under is non-free (only "JJ2000 Partners" have
    right to use, there is no right to modify, heavy use restrictions based
    on standard compliance).
  2. JPEG 2000 is heavily patent mined.
    For use non free code if such usage restriction makes the license incompatible with The Open Source Definition and The Free Software Definition. Because thredds/grib library distribution includes this software, it effectively becomes proprietary software itself.
    thanks in advance
    regards

Not much we can do about jj2000. The grib module, which uses jj2000, is optional for netcdf-java library. You can leave it out if you need to. Let us know if you need us to to do something for that.
