It is possible to create a job which will never end by configuring a job like:

job {
	name "Test"
	configure { root ->
	     // Please note I forgot to start with "root"
		(properties / 'hudson.plugins.disk__usage.DiskUsageProperty').@plugin="disk-usage@0.23"
	}
}

I did obviously a mistake in the configuration block since I start with "properties" instead of "root". Neverless it would be good if in this case the job would just fail.
