23422	[Patch] ParallelWayAction should not store a reference to MapView	GerdP	team	"==== What steps will reproduce the problem?
1. Start JOSM
2. open data layer (this creates an instance of MapView)
3. close data layer
4. create heapdump
==== What is the expected result?
MapView instance is garbage collected
==== What happens instead?
Field ParallelWayAction.mv still refers to the MapView instance and MapView may refer to all kinds
of objects because of listeners.
==== Please provide any additional information below. Attach a screenshot if possible.
