[IDV #JSO-122092]: BUFR-coded ASCAT wind file cannot display or list with the newest netCDF/java libraries. [1387]

Bob,

This is fixed in netCDF 4.3. 

Best Wishes,

Unidata IDV Support

> Hello -
> 
> We received a report that a BUFR-coded ASCAT file wasn't working in our new 
> nightlies after updating the IDV, and thus the netCDF/java libraries.  This 
> file worked without error before the update, and it also produces an error in 
> the IDV.  One of our programmers believes that this is a netCDF/java library 
> issue, so I am also going to send an email to them to see what they have to 
> say. I will update this inquiry with information as I hear anything.
