> According to java.sql.DatabaseMetaData, the following DatabaseMetaData
> methods should not allow tablename=null:
> getBestRowIdentifier, getColumnPrivileges, getIndexInfo, getVersionColumns,
> getPrimaryKeys, getImportedKeys, getExportedKeys. In the five former methods,
> SqlExceptions are thrown if tablename == null, but this check is not
> performed in the latter two.
> The method calls eventually end up in EmbedDatabaseMetaData, which performs
> this check. Hence, an exception is thrown either way. If we want the
> exception to be thrown as early as possible, the two latter methods should do
> so as well. If not, the check should be removed from the former methods.
