[GRASS5] rasters?

[Andrea Antonello]

> What are you asking, exactly?

Alright, thanks Glynn.

About two years ago I wrote the raster reading of GRASS in java for JGrass. 
For the last to years everything worked flawless. 
In the last months something stopped to work, i.e. when the java library tries 
to read a raster map, it fails at the point of uncompressing the raster row.
Since it worked properly in the past years, I expect that something was 
changed in the GRASS libs, so I was asking if anyone knows what that 
something could be, in order to be able to understand and fix is.

Regards,
Andrea
