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.
