grails sessionFactory.currentSession.flushMode not work with thread?

In grails we have the following config:

DataSource.groovy: 

hibernate {
    flush.mode="commit"
}

which prints "COMMIT" when we log it in a transactional context: 

println "session=${sessionFactory.currentSession.flushMode}"

but when we create a new thread

this prints "AUTO".

New thread does seem to get the other hibernate settings, ie database, username and factory, but the currentSession doesn't take the flush.mode setting.

Can anyone advise?

Are you using the Quartz plugin?

Quartz changes the flush mode: https://fisheye.codehaus.org/browse/~raw,r=41198/grails-plugins/grails-quartz/tags/LATEST_RELEASE/src/java/org/codehaus/groovy/grails/plugins/quartz/listeners/SessionBinderJobListener.java

public void jobToBeExecuted(JobExecutionContext context) {
    Session session = SessionFactoryUtils.getSession(sessionFactory, true);
session.setFlushMode(FlushMode.AUTO);
    TransactionSynchronizationManager.bindResource(sessionFactory, new SessionHolder(session));
    if( LOG.isDebugEnabled()) LOG.debug("Hibernate Session is bounded to Job thread");
}

The workaround is to change the flush mode in the Job:

        def sessionFactory
        .
        .
        .
        def session=SessionFactoryUtils.getSession(sessionFactory, false)
        session?.setFlushMode(FlushMode.COMMIT)
