Bamboo restart does not startup the plugin correctly

I'm not sure under what circumstances this is caused. We need to investigate it a bit more. But it's happened our our Bamboo. You get the following after a Bamboo restart and running a build that makes use of SR:

Could not execute task 'Filters according to files committed' no Plugin with key 'com.onresolve.bamboo.groovy.groovyrunner:task.configuration' is installed.

The fix for this was to run the contents of startup/RegisterComponents.groovy in the script console. You can see if this module: filteringPreBuildQueuedAction is not there in UPM, then you need to run that script.

SR should startup properly each time it is installed and on a restart without any manual intervention.
