Comment 3 matthias42 2013-01-13 18:46:32 UTC 
This looks like a typical jdbc driver problem - returning NULL as productname seems not to be sensible - whatever...

If the start of line 505 is changed from

            if (dmd != null) product = dmd.getDatabaseProductName().trim();

to

            if (dmd != null && dmd.getDatabaseProductName() != null) product = dmd.getDatabaseProductName().trim();

this bug can be closed. I don't see how else a NULL Pointer Exception could be created.
