-----------------------------------
Are you running JDK 7 by chance, Bill?
I have noticed the same error when trying to use Snappy as the compression
codec with Avro Tools on a Mac with Oracle JDK 7 (but not when using JDK 6):

Running the exact same command line with Sun JDK 6 on my Mac works just fine.
