Java EE heap dump on Out of Memory

Question

I am using EJB v3.1. Application is running in JBoss. I'm also using Wildfly. As I understand all System Exceptions including OutOfMemoryError are wrapped in EJBException. I set jvm parameters to get heap dump on Out of Memory like this: -XX:+HeapDumpOnOutOfMemoryError but it doesn't work. I suppose because it is no longer OutOfMemoryError but EJBException.
How do I get this working in jave ee? Also should i get the heap dump when throwing new OutOfMemoryError?
