Do instance variables set in @PostConstruct need volatile?

[Ed Slavich]

Hello,

When a bean instance variable is set in a @PostConstruct method, does the 
variable need to be declared volatile?  For example:

@Stateless
public class SomeBean {
    private volatile Foo foo;

    @PostConstruct
    private void initialize() {
        foo = new Foo();
    }
}

Or does TomEE provide some sort of guarantee that makes volatile unnecessary?

Thanks,
Ed
