Annotation @PostConstruct is a general annotation used in any dependency injection mechanism. The Javadoc explicitely states that, unless used within an interceptor, it must be put on a method, which has void return type and throws no checked exceptions.

It is weird that Spring allows checked exceptions on post-construct methods, as there is not way how to handle them. But as this requirement is only a validation and can be ignored, Spring probably ignores checked exceptions and Glassfish does not. There is possibly an unnecessary Glassfish feature, that it scans and validates all classes, even if not used in CDI or any other mechanism (EJB, ...)

The best is to remove checked exceptions to align the code with the documentation and make it portable.
