Comment 2 Bill DeCoste 2013-02-21 00:39:08 UTC 
Use kill -9 instead of kill - TERM if graceful shutdown fails
Comment 3 Mike McGrath 2013-06-24 19:34:16 UTC 
Moved during bug triage meeting

Lifecycle demo code
Comment 5 Dan Mace 2013-07-09 19:41:00 UTC 
I'm closing this issue as NOTABUG, and have attached example code which can be added to a jbossas-7 application demonstrating the lifecycle methods. The code provides a LifecycleDemo class which is a @Singleton/@Startup EJB.

When the example code is built and deployed, the following output will appear in the JBoss server.log during startup, demonstrating @PostConstruct:

2013/07/09 15:34:41,027 INFO  [stdout] (MSC service thread 1-1) !!!!!!!!!!! in postconstruct

When an `rhc app stop` is issued to the application, the following output will appear in the JBoss boot.log demonstrating @PreDestroy:

15:34:59,821 INFO  [stdout] !!!!!!!!!!! in predestroy

The jbossas-7 cartridge issues a SIGTERM to the container for shutdown, which is equivalent to using the JBoss CLI 'shutdown' command. This is a graceful shutdown, and the lifecycle is honored in both cases.
