Hello,

I had sent an email regarding this issue a while ago and updated to the 4.1 
candidate 2 library to fix it, and it seems to have been fixed for the Hawaii 
files I am using from the National Weather Service's NDFD.  I am receiving an 
AIOOB Exception when calling the readDataSlice method for Guam, though.

The GRIB2 file is attached and the stack trace can be found below.
