Mike Matrigali resolved DERBY-5494.
-----------------------------------
Resolution: Fixed
Fix Version/s: 10.10.0.0
10.9.1.1
Fixed in 10.10 and backported to unreleased 10.9 branch prior to 10.9 being
released. Because of
change in behavior in syncing and extent of changes I don't think we should
backport the changes for
DERBY-5780 or DERBY-5494 to 10.8 or previous.
> Same value returned by successive calls to a sequence generator flanking an
> unorderly shutdown.

> The following sequence of steps causes a sequence generator to return the
> same value on successive NEXT VALUE FOR calls.
> 1) Bring up ij and issue the following commands:
> connect 'jdbc:derby:db;create=true';
> create sequence s;
> values next value for s;
> 2) Control-c out of ij so that the engine comes down hard without an orderly
> shutdown.
> 3) Now bring up ij again and issue the following commands:
> connect 'jdbc:derby:db';
> values next value for s;
> Thanks to Knut for finding this one.
