Description

Some of the language result sets cache the current isolation level in their constructors. To allow reuse of the result sets, they should check the isolation level each time they are opened. Currently, this affects HashScanResultSet, TableScanResultSet, LastIndexKeyResultSet and UpdateResultSet (and their sub-classes).
