[netCDFJava #WWW-347958]: Problem with attributes of type CHAR



No it is not obvious because of where we put our snapshots.
Anyway, I think this is correct. Look at 
https://artifacts.unidata.ucar.edu/#browse/browse:unidata-snapshots:edu%2Fucar%2FnetcdfAll%2F5.0.0-20181017.203038-305



> 
> I'm sorry if the question is obvious but, how can we use the library with 
> this modification? Do we have to compile the code ourselves? When is planned 
> to release a new version including this fix?
> 
> Thank you very much for your help.
