using Java EE BeanManager as Singleton

In my Java EE aplication I use the following snippet to obtain BeanManager

public static BeanManager getBeanManager() {
    try {
        InitialContext initialContext = new InitialContext();
        return (BeanManager) initialContext.lookup("java:comp/BeanManager");
    } catch (NamingException e) {
        throw new RuntimeException("Failed to retrieve BeanManager!", e);
    }
}

Would it be safe to use BeanManager as singleton, so I would not have to lookup in initial context each time I need BeenManager?

If you want to use the BeanManager into a standard EE(v6-v7) component then it is perfectly legal and recommended to simply do:

@Inject BeanManager beanManager
