Volker Kleinschmidt commented on AMQ-3189:
------------------------------------------
This isn't an improvement, it's a bug.
While the createTablesOnStartup option provides a workaround, it's not a good
one, since it means you need to have that to true initially, then change it to
false later to avoid the annoying logged errors. Not suitable for mass
deployment.
It's pretty harmless though - merely annoying. But it's also trivial to fix
(see my previous comment). Just something to fix for goodwill...
> Postgresql with spring embedded activeMQ has "table already created" exception
> ------------------------------------------------------------------------------
>
> Key: AMQ-3189
> URL: https://issues.apache.org/jira/browse/AMQ-3189
> Project: ActiveMQ
> Issue Type: Improvement
> Affects Versions: 5.4.2
> Environment: Postgresql 8.4, latest Postgresql JDBC9.0.x, tomcat
> 6.x, spring 2.5
> Reporter: steve neo
>
> This may not a bug as MQ is still workable after this exception warning.
> However, can you suppress the exception stack in log? It even can not be a
> kind of "warning" as this is just a normal process to detect if tables exist
> or not.
> Same configuration works fine with MySQL. For postgresql, first time starting
> will create table without problem After restart tomcat, log prints some
> annoying failure message with long exception stack.
