Description alexismp 2009-11-09 07:40:02 UTC

(NB6.8beta)
In a Java EE managed bean (EJB, JSF managed bean, plain managed bean, etc...), methods annotated with @PostConstruct (@PreDestroy) are always marked as not used, while in fact they always are when executed in a container.

5 duplicates - I think this deserves some consideration.

I must agree. Number of complaining users is growing.

Comment 9 misterm 2015-05-08 05:21:00 UTC

I can confirm this is really cumbersome. I like my error stripes clean, but some less experienced developers on the team might think these methods need some cleaning.

This issue should be expanded, based on duplicates such as 176241, as to cover unused Java EE boilerplate, such as @Id as well. Also notice any persistent fields on entities which are assigned are useful since they can be queried.

Comment 10 Svata Dedic 2015-09-22 15:26:59 UTC

Moving to java.source, marking as high prio ENHANCEMENT. There has to be a common API for specification-defined usage and / or names. E.g. 

* hints check naming and access rights, which might be defined by some technology (c.f. serialVersionUID)
* editor highlights unused symbols, which can be marked by annotations or injected in some special subtypes (c.f. @Autowired)

Not sure whether the API should allow to extend "usage" relationship to capture real usage of fields outside plain java access, i.e. Spring configuration for a property accesses setter etc.
