Hello.
Please review the fix for jdk/client.

Bug: https://bugs.openjdk.java.net/browse/JDK-8198334
Fix: http://cr.openjdk.java.net/~serb/8198334/webrev.01

These tests were broken due to the product bug JDK-8198335 [1]
which was fixed in jdk11, so we can clean the problemList.

One tests required some additional clean up since it was mentioned
in another bug JDK-8213514 [2]
