Description:
We have a MySQL server instance with a database CIA and a table COUNTRY.  If I issue the call
   getTables( "CIA", "%", "%",null)
I get a ResultSet with one row of catalog CIA schema null table COUNTRY, as expected.  If I issue the call
   getTables( "FOO", "%", "%",null)
I get the following in LogWriter:

**********
DriverManager.getConnection("jdbc:mysql://ftg.selectbs.com:3306/CIA")

**********

I would expect to simply see an empty result set.

The same exception is thrown for getColumns() wit the same parameters.  In fact the above stacktrace came from a getColumns() call.

How to repeat:
Reproducible case given in description.

Suggested fix:
None.
