unorderly shutdown.

                 Key: DERBY-5494
                 URL: https://issues.apache.org/jira/browse/DERBY-5494
             Project: Derby
          Issue Type: Bug
          Components: SQL
    Affects Versions: 10.8.2.2, 10.8.1.2, 10.7.1.1, 10.6.2.1, 10.6.1.0, 10.9.0.0
            Reporter: Rick Hillegas


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.
