Description
The change JDK-8129822 https://bugs.openjdk.java.net/browse/JDK-8129822 introduced a jtreg keyword to mark tests as requiring a "headful" (as opposed to "headless") environment to be able to run. But a number of jdk10 jtreg tests from java/awt and javax/swing miss this keyword and run into "headless environment" exceptions and fail when running in a headless environment. Suggestion is to add the keyword to fix this. Tests / exceptions : java/awt/Choice/ChoicePopupLocation/ChoicePopupLocation.java java.awt.HeadlessException at
