Rich DiCroce commented on AS7-5063:
-----------------------------------

I've just discovered a nasty EclipseLink bug. There are more details here (http://www.eclipse.org/forums/index.php/m/905614/), but the short version is that there's a race condition in EclipseLink's JPQL parser that can occur when a persistence unit is first initialized. My project has a pair of @Singleton @Startup EJBs that both need to query the database as part of their @PostConstruct, and they hit this bug very consistently on AS 7.1.1.Final. The guy who started the linked forum thread said he was going to file a bug report. I asked whether he actually did that, because I can't find one. If he didn't or he doesn't answer, I'll create a new issue in Eclipse's bug tracker. In the meantime, I've added a hack to work around the issue (source available at the link) that could be packaged as part of the integration module.

> For EclipseLink to properly identify the container and set up correct transaction integration, etc, it needs the property "eclipselink.target-server" to be set to "JBoss".
> There's an open issue asking EclipseLink to auto detect the container (https://bugs.eclipse.org/bugs/show_bug.cgi?id=383257) but right now, a simple solution to making EclipseLink work well on AS7 is for AS7 to pass that property to EclipseLink.
> That'll help prevent issues and confusion like this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=365704
> Users can set it as a system property right now as shown on bug 383257, but really it'd be best if JBoss passed it to the persistence unit during creation.
> Time permitting I'll give this a go.
