I can see two alternatives for us:
1. Ship 10.2 on the current schedule but do not include the JDBC4
drivers. When run on Java SE 6, Derby 10.2 would continue to expose
our JDBC3 implementation. In addition, we would remove JDBC4-specific
documentation from our user guides and prune out the JDBC4-specific
javadoc.
2. Delay the current 10.2 schedule until after JDK 6 goes GA. At that
time we could release a version of Derby which includes JDBC4 drivers.
Given the length of time since 10.1 was released, the uncertainty of
the exact date of JDK 6 shipment, and the number of new features
included in 10.2, I think that (1) is a better plan. Of course, this
is up to the community to decide.
I do not think we have enough user feedback for 10.2 release just based
on regression risk. We heard that the JDO tests passed and the Torque
tutorial ran. We got a few questions on the list about how to
upgrade. We got serious feedback from a single user who reported
multiple serious optimizer regressions. That's it as far as I can tell
from users. We got quite a few regression reports from development that
folks stumbled upon.
Many of these regressions sadly have already made their way into 10.1.3
and therefore are being picked up by users for production. If this were
a medical trial for a blood pressure medicine and not a database what
would we do? Our one patient in the trial of our next generation
medication is finding multiple issues that have made him very sick and
we find that many of these same regressions are in pharmacies now. I
think we need to notify the user community of the situation, try to get
more user input on 10.2 and flush out more regressions. We port fixes
to 10.1 to try to get it to a stable state and then release 10.2. Also
any ideas anyone has for new optimizer tests would be good and folks
could write those.
Those are all my ideas for now. It could be that lots of users have
tried 10.2 without problems but haven't reported in and then it is just
a matter of getting them to speak up. I will work to rattle the bushes
around here and please ping groups where you work and ask them to try
10.2. I will also send a message to the user list to try to get more
user input.
