bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7149068 webrev: http://cr.openjdk.java.net/~denis/7149068/webrev
There are a timing issue and a problem with usage of Util.clickOnTitle() method. It is specified in the comments for the method that windows should have enough width. The test was introduced in jdk7u and it is absent in the jdk8 forest, so the webrev contains no diffs only a new version of the test.
I have run the test with Jtreg suite. The test passes. Thank you, Denis.
