JOSM can't delete old and replace by new plugins

[willis@…]

After updating plugins and restarting JOSM I get the appended output on the console. After exiting JOSM I can manually delete the old x.jar and rename the new x.jar.new to x.jar. After this JOSM starts and uses the new version without problems.

In the German forum the same problem has been reported ​http://forum.openstreetmap.org/viewtopic.php?pid=98763#p98763.

Console output (for wmsplugin):

I have the same problem on Win XP. (Under Ubuntu, I've never got this problem, till now.)

(In [3512]) fixed #5373 - JOSM can't delete old and replace by new plugins (JOSM loaded icons from plugin jar file, but did not release file handles.)
