Hi Sergey/Phil,

Thanks for pointing that out. I have created a new webrev: http://cr.openjdk.java.net/~kaddepalli/8197808/webrev01/
 with the appropriate changes for ProblemList.txt as well.

I have tested on Windows 7, Ubuntu 16.04, Ubuntu 17.10 and MacOS 10.13, and the test passed with/without my changes.
As noted earlier, on Windows 10, the test passes after the fix.

Yes .. even if bugs were added to the problem list in bulk, the expectation is that they'll be removed by the bug fix that fixes the failure.
And if it still fails on some platforms then either (1) you aren't done with your fix, or (2) you need to find a different bug ID under which to now exclude the test for the platform(s) that still fail for what would normally be some completely un-related reason.

Other than that the fix is fine.
