In the 10.8 branch, back out the concurrency improvements introduced by using
SequenceUpdaters to allocate identity values.
---------------------------------------------------------------------------------------------------------------------------
Key: DERBY-5448
URL: https://issues.apache.org/jira/browse/DERBY-5448
Project: Derby
Issue Type: Bug
Affects Versions: 10.8.2.1
Reporter: Rick Hillegas
New errors were seen while running NsTest against the 10.8.2 release
candidates. These errors are recorded as DERBY-5430 and DERBY-5422. The first
error is a deadlock which occurs when inserting into the main table of the
test. The second error is a problem clearing the identity cache. These errors
have caused people to lose confidence in the concurrency improvements
introduced by DERBY-4437. We should back the DERBY-4437 changes out of the 10.8
branch and use the trunk to continue debugging the problems disclosed by NsTest.
