22529	[Patch] possibly improve performance in class `ChangesetDataSet`	GerdP	team	"When reading changesets, JOSM repeatedly may call method getPrimitiveId() for the same object in `ChangesetDataSet.put()` which is called when a changeset is read. Unless the run time optimizer can kick in this method creates a new `SimplePrimitiveId` instance each time it is called. The patch creates a single instance and uses `map.computeIfAbsent()` as recommended by sonarlint.
