I've traced the extra queries to these two lines in Column.java:
this.nullAllowed = rsmd.isNullable(columnNumber) == 1;
this.autoIncrement = rsmd.isAutoIncrement(columnNumber);
I checked the source of the old driver; it hard-codes the
results of those queries, so this.nullAllowed and this.autoIncrement
are always set to false.
So I made this modification:
this.nullAllowed = false; // rsmd.isNullable(columnNumber) == 1;
this.autoIncrement = false; // rsmd.isAutoIncrement(columnNumber);
And it works! No more extra queries.
Problem solved - for me, anyway.
Thanks for the hints.
