Hey Craig,
I don't know how DataNucleus tries to cancel a query.
jdbc.sql.Statement.cancel() is an optional method which some DBMSes
implement but Derby doesn't. The method raises a "Feature not supported"
exception according to
https://db.apache.org/derby/docs/10.17/ref/rrefjdbc40794.html
Hi,
The JDO project is having some issues with a feature that was never formally
tested: cancel query. It is intended to allow the JDO user to cancel a query
from a different thread. It is an optional feature enabled by a user
configuration flag.
The problem is that it does not seem to work.
