public class JiraImportProgressFilter
This filter is used to report on progress of a data import. It has to live in a filter first in the filterchain
since otherwhise we run the risk of having another filter call through to the ComponentManager. This could cause
deadlocks in pico while the ComponentManager is being restarted during the data import! This filter basically checks
if there's currently a data import task in progress and will show progress if there is. Otherwise it simply
redirects to the dashboard.
