Description copied from interface: Destructible

Perform arbitrary clean-up logic upon component destruction by the framework.

Note that Destructible.destroy() method may be called outside of UI thread, e.g. when the whole instance of admincentral gets disposed as result of heartbeat checks. This means that neither Magnolia, nor Vaadin thread locals will be reliably present upon that method invocation.
