---------------------------------------
With IBM 1.6 on linux I saw a similar trace to this in the log of a failed
stress/stress.muilti
run. It may be the same bug.

> This is a long transaction that has suddenly started throwing a NPE.
> Nothing strange happens during the transaction, but on closing I get
> the NPE.
> If I reorder some of the statements in the transaction (keeping
> functional equivalence) the NPE is sometimes not thrown.
> I have already moved any table/index create statements to a different
> (previously committed) transaction. (I have had a few NPE before and locking
> issues that led me to this practice).
> For a while I thought that shutting down derby after creating tables solved
> the problem, but this has been proven false.
> I have tried to run with a sane version, but then I am blocked by too many
> DERBY-3360.
> Also:
> On occasion the transaction DOES commit. Or seems to, but then Derby becomes
> unresponsive, the db files do not grow, but CPU rises and new connections can
> connect but get no response to commands. I don't know if this is really
> connected or not, but I thought I would mention it, as this unresponsive
> problem is what I am supposed to be diagnosing. When I say seems to commit, I
> mean that sometimes commit returns, sometimes it doesn't. Not very helpful, I
> know.
