How do you set a shutdown hook for jboss when @PreDestroy is too late?
We have some service cleanup that needs to be performed when JBoss shutsdown. We had implemented a @Singleton bean with a @PreDestroy method to handle this cleanup, but it appears that this is too late in the shut down process.
We're trying to unbind some components from JNDI and make a call to a remote EJB.
Unbind fails with:
Caused by: javax.naming.NamingException: JBAS011836: Could not resolve service service jboss.naming.context.java.xxi.modules.BttbTaskWorkerModule

We also try to issue a remote EJB call and get this:

This sounds the same as:
https://community.jboss.org/thread/196856
It reccomends using @DependsOn, but what would I depend on to ensure the NamingStore has not already been destroyed?
Or is this to be fixed in a later release? https://issues.jboss.org/browse/WFLY-1247
