Knut Anders Hatlen commented on DERBY-6125:
-------------------------------------------

Thanks, Dag.

With the patch, it looks like the Sqlca.sqlWarn_ field is never set, so 
getSqlWarn() recalculates the value on every call. If that's intentional, the 
field should probably be removed now. If not, the caching of the return value 
should be reintroduced (and the type of the field changed from char[] to 
String, I suppose).
