This is old code that I remember I took some portions and heavily optimized.
It came from this (dead?) library to read/write Grib files:
http://jgrib.sourceforge.net/

it is LGPL 2.0

The license of that portion of ImageIO-Ext is BSD, see:
https://github.com/geosolutions-it/imageio-ext/blob/master/library/imagereadmt/LICENSE.txt
https://github.com/geosolutions-it/imageio-ext/blob/1.1.13/library/imagereadmt/src/main/java/it/geosolutions/imageio/imageioimpl/imagereadmt/ImageReadOpImageMT.java

since the original ImageRead operation code was BSD like:
https://java.net/projects/jai-imageio-core/sources/svn/content/trunk/LICENSE.txt?rev=254

No idea, I actually checked the license of the original NetCDF
RandomAccessFile class.
If this is a blocker we can go back and reimplement this class.

Let me know if you need me to dig further.
