-----------------------------------
Attachment: softupgradefix_v2.diff
I have attached a new version of the patch, softupgradefix_v2.diff. In addtion
to the fix described above. It removes the method
DRDAResultSet#getRsDRDATypes() in order to avoid similar mistakes in the
future. After the fix, this method was no longer in use.

> Components: Network Server
> Affects Versions: 10.3.0.0, 10.3.1.0, 10.3.1.1
> Environment: Client/server soft upgrade
> Reporter: Øystein Grøvlen

> Select operations with client/server and soft upgrade mode will not see first
> byte of the Blob/Clob if the LOB column is nullable.
> The reason seems to be that during soft upgrade, the network server does not
> prepend the LOB data with the byte indicating whether the column is null or
> not. Hence, the first data byte will be interpreted by the client as the
> null byte, and the reading of the LOB will start at the second byte.
