+bufr-3.0.jar has been modified from the released 4.2 version of the UCAR BUFR IOSP.
+The java file ucar.nc2.iosp.bufr.tables.BufrTables has been modified to fix a bug
+in the getWmoTableB(int) method. The modified java source file is included along
+side the class files in the jar. This was done under ticket #2905.
+
+The bug involves an inconsistency in logic when choosing the key to the Table B
+version map. This results in the version 14 Table B being replaced by
+the version 13 Table B. The code has been rewritten in newer versions (4.3,4.4).
+This fix is not a long term solution. Moving to later versions isn't an immediate option
+due to an issue retrieving time and location information in those versions.
+The time and location variables are not populated in the structure variables.
+A post has been made to the netcdf-java mailing list inquiring about the
+issue. Another roadblock is the grib dependency on the UCAR grib library. The grib
+API has changed in the later versions and would require reworking and testing
+the grib 1 decoder. Aside from those issues, later versions of the library
+also require updating the joda.time jar used by ws-security and adding the
+google protocol buffer library and jdom2.
