12245	JOSM stalls when loading child relations	lapinos03@…	team	"Hi there !

My JOSM stalls when I try to download the child relations in a relation (Edit relation dialog box). Tested with v9060 and v9181 today (2015/12/28) and yesterday (java8 update66).
After clicking the ""Download all children"" button, the popup appears showing the progressing bar and stays forever.
IMPOSSIBLE to cancel (button)
IMPOSSIBLE to close that popup
IMPOSSIBLE to quit the app.

Console trace for this action :
