12279	JOSM hangs when opening a large file	Adrian	team	"==== What steps will reproduce the problem?
1. Launch JOSM
2. Open a large file (~60MB in .osm format)

==== What is the expected result?
The file is opened after a short wait.

==== What happens instead?
JOSM hangs at 100% CPU. It still has plenty of memory available when it hangs.

==== Please provide any additional information below. Attach a screenshot if possible.
This was OK in r9060. 10MB is still OK with r9229.
