@prrace Could you please take a look at the proposed changes! Is this fix needed or not? It fixes JDK-8165943/JDK-6598756. I opened PR on JDK-8165943 because it had more active conversation. But maybe I made a mistake and it should be opened on JDK-6598756 (created by you) because it was created earlier then JDK-8165943?
