------------------------------------
Assignee: Marshall Schor
> destroy method of shared resources never called
> -----------------------------------------------
>
> Key: UIMA-2977
> URL: https://issues.apache.org/jira/browse/UIMA-2977
> Project: UIMA
> Issue Type: Bug
> Components: Core Java Framework
> Reporter: Richard Eckart de Castilho
> Assignee: Marshall Schor
> 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).
