> {{ReconfigurableBase#startReconfigurationTask}} does not update its cached configuration after a property is reconfigured. This means that configuration values queried via {{getConf().get(...)}} can be outdated. One way to fix it is {{ReconfigurableBase#reconfigurePropertyImpl}} returns the new effective value of the config setting and caller i.e. ReconfigurableBase will use it to update the configuration.
