13491	"""EDT violation detected"" in self compiled r10916"	GerdP	team	"==== What steps will reproduce the problem?
1. checkout r10916
2. ant clean dist
3. cd dist 
4. java -jar josm-custom.jar
5. Load attached slow1.osm
6. Press Shift+V (Validate)
7. Left-Click on the line ""Warnings (2,481)"" to select it
8. Click on ""Fix"" Button

==== What is the expected result?
Dialog Box shows ""Fixing errors ... "" with a counter that quickly finishes and disappears
==== What happens instead?
The expected dialog box appears but the errors are fixed very slowly.
In the command line windows I see several ""EDT violation detected"" messages followed by tracebacks (see attached log which also shows some messages produced by the ant clean dist step).
==== Please provide any additional information below. Attach a screenshot if possible.
The problem doesn't appear with josm-latest.jar file from http://josm.openstreetmap.de,
this file is also much smaller (~1 MB). 
I see the same problem when I build and execute in Eclipse.
