 This error may be due to a batch that is greater than 32k.

not show this failure. It looks like this failure is occuring only with JCC2.6. 

This is probably caused by my recent change to fix DERBY-428.

I only have JCC 2.4 on my system, and not JCC 2.6.

Is there some information on how to set up my system so that I can run with both
JCC 2.4 and JCC 2.6?

In the meantime, I think that the simplest thing here might be just to modify the
test. The DERBY-428 regression test attempts to submit a single batch with as
many possible batch elements as can fit.

However, I was not able to find a clear specification of how many batch elements
can fit, so I was experimenting with the different drivers to figure out how
many each one supports.

Apparently JCC 2.6 supports fewer batch elements than did JCC 2.4?

Deepa, if you can figure out how many batch elements are supported by JCC 2.6,
I think it would be perfectly reasonable to modify the prepStmt test to submit
a batch of that size.

Let me know how I can help further with this problem.
