> I am using an inhouse platform which manage the life cycle of ignite instance
> by calling ignition.start() and ignition.stop() from a web application.
> it could be started without issue for the first time. however, if it stop the
> ignite by calling ignition.stop() and followed by destroying the parent

> Walk through into Ignite code, it should be caused by a static thread group
> created in IgniteThread class. (private static final ThreadGroup DFLT_GRP =
> new ThreadGroup("ignite")
> Destroyed the parent thread group which start the ignite instance will result
> in causing the DFLT_GRP go into destroyed state. Therefore, when Ignite was
> start ifor the 2nd time, this static thread group has been destroyed and no
> longer able to run the ignite.
