> Client tries to reuse a statement for sending SET CURRENT ISOLATION statements to the
server.  There must be some problems with this logic where it is trying to use a closed statement.
 Perhaps an overall better strategy would be to use an EXCSQLSET to send the set commands
to the server and then invoke the embedded JDBC setTransactionIsolation call on the server
as Oyvind did for setQueryTimeout.  Using the SET ISOLATION statements on the client has caused
a variety of problems.
