Re: [netcdf-java] grib2

Ah, interesting. You've changed the order of tika and netcdfAll-4.3 in the
classpath listing, so now Java is finding the v4.3 classes BEFORE the v4.2
classes. Both are still there, but java's not seeing the 4.2.

As I'm sure you know, relying on such things for proper execution of your
program is NOT recommended. I'm glad that you're trying to get a "proper"
fix in place on the Tika side of things.

Cheers!
Christian
