[jira] Created: (OPENJPA-1372) Generating identifiers by using
sequence table may fail during sequence table initialization
Generating identifiers by using sequence table may fail during sequence table initialization
--------------------------------------------------------------------------------------------
Key: OPENJPA-1372
URL: https://issues.apache.org/jira/browse/OPENJPA-1372
Project: OpenJPA
Issue Type: Bug
Components: jdbc, kernel
Affects Versions: 2.0.0-M3, 1.2.1
Reporter: Milosz Tylenda
When sequence table does not exist and mutliple threads get EntityManagers from EntityManageFactory, an insert into sequence table may fail because of duplicate primary key value.
EMF is created lazily by default and users reported various problems with concurrent initialization (e.g. failures in resolving aliases in JPQL queries, IIRC) of EMF. This issue might have the same roots.
Issue and test case originally reported by Pinaki in OPENJPA-466.

[jira] Resolved: (OPENJPA-1372) Generating identifiers by using
sequence table may fail during sequence table initialization
Posted by "Michael Dick (JIRA)" <ji...@apache.org>.

Michael Dick resolved OPENJPA-1372.
-----------------------------------
Fix Version/s: 2.0.2
2.1.0
Resolution: Fixed
Testcase added to 2.x releases - so I'm marking as resolved. If there's another way to trigger this problem we can either open another issue (if 2.0.2 or 2.1.0 have been released), or reopen this one (if neither has been released).
