21234	"During ""OK"" click in preference window. Should catch errors (Tag Checker Data Sources) without closing the preference window."	reichg	team	"Reproduce:

1) Open JOSM and go to edit -> preferences -> Data Validator
2) Input invalid text into the ""Data Sources"" field within the Tag Checker Test
3) Click ""OK"".
4) Notice error pop up but the whole preferences window closes. 

Expected Behavior:

1) Input invalid text into the ""Data Sources"" field within the Tag Checker Test
2) Click ""OK"".
3) Notice error pop up
4) exit error popup and keep preference window open. 

In general while running through validation during the ""OK"" button click we should keep the preference window open so the user doesn't have to come back to preferences to fix the issue."	defect	new	normal		Core
