> When using @Startup and/or @Singleton to start a Bean on server startup, everytime a method is accessed or the bean is injected with @EJB, both Constructor and @Postconstruct are executed.
> This happens multiple times, each time any component uses the Singleton bean.
> This seems similar to an issue reported for JBOSS AS 7.x (see forum link reference below)
