If a result set has more than 70 columns, the implementation of getExtendedFieldInfo in FBResultSetMetaData will break this up into querying per 70 fields. However, the code has a bug where it will start over with column 1, so it will query the columns it already queried, instead of querying the next 70 columns.

Since this bug seems to have existed since Jaybird 1, and there is graceful degradation, this will only be fixed in Jaybird 6.
