PooledLoOptimizer in conjunction with SequenceStyleGenerator is not thread-safe ------------------------------------------------------------------------------- Key: HHH-5929 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5929 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.1 Environment: Hibernate 3.6.1, Java 6, Mac OS 10.6.6 Reporter: Robin Sander The generate method of the PooledLoOptimizer introduced in 3.6.1 is not synchronized in difference to the one in PooledOptimizer and in other Optimizer implementations. The problem is that some IdentifierGenerator implementations have themselve a synchronized generate method (like SequenceHiLoGenerator e.g.) and some don't, like the new SequenceStyleGenerator. According to the javadoc IdentifierGenerator implementations have to be thread-safe. Now I don't know if there is any agreement among the developers whether this thread-safety is to be achieved in the IdentifierGenerator itself or in the Optimizer most of them delegate to but what I know is that SequenceStyleGenerator in conjunction with PooledLoOptimizer is not thread-safe because neither of them guards against concurrent access in any way. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
