>             Project: UIMA
>          Issue Type: Bug
>          Components: Core Java Framework
>            Reporter: Richard Eckart de Castilho

>              Labels: Resources
>             Fix For: 3.0.0SDKexp
> Apparently the ResourceManager and the resources created by the manager do 
> not participate in the usual component life cycle. On other components, such 
> as analysis engines or readers, the destroy() method is called when the 
> component is disposed of. External resources never get notified when they are 
> no longer needed. At least any resources derived from Resource (e.g. 
> DataResource and ParametrizedDataResource) should be notified. The 
> SharedResourceObject interface does not define any such life cycle callback.
> As a side-note: An alternative to the rather heavy-weight Resource interface 
> of UIMA maybe be small life cycle interfaces such as the Spring 
> InitializingBean and DisposableBean interfaces, or Java annotations marking 
> initialization and destruction methods (e.g. @PostConstruct and @PreDestroy).
