JDK-8064468 - ownedWindowList access requires synchronization in Window.setAlwaysOnTop() method
Description
Windows owned by an always-on-top window DO NOT automatically become always-on-top.

From the spec for java.awt.Window.setAlwaysOnTop(boolean):

"All windows owned by an always-on-top window inherit this state and automatically become always-on-top."

The following testcases fail due to this issue:
api/java_awt/Window/indexTGF.html#AlwaysOnTop[ownedAlwaysOnTop]
api/java_awt/Window/indexTGF.html#AlwaysOnTop[masterCeasesAlwaysOnTop]

Seems like this is simply not implemented.

EVALUATION The problem is reproducible. Should be investigated.

EVALUATION We have no JCK8 builds just yet, so information about test suite cannot be provided. Please, see mini-test attached import java.awt.*; public class AlwaysOnTopTest { public static void main(String[] args) { test1(); test2(); } private static void test1() { Window frame = new Frame("Frame"); frame.setSize(200, 200); frame.setAlwaysOnTop(true); frame.setVisible(true); waitAWhile(); Window dialog = new Dialog(frame, "owned"); dialog.setSize(200, 200); dialog.setLocation(100, 100); dialog.setVisible(true); waitAWhile(); System.out.println(String.format( "frame.isAlwaysOnTop() = %s; dialog.isAlwaysOnTop() = %s", frame.isAlwaysOnTop(), dialog.isAlwaysOnTop() )); frame.dispose(); dialog.dispose(); waitAWhile(); } private static void test2() { Window frame = new Frame("Frame"); frame.setSize(200, 200); frame.setVisible(true); waitAWhile(); Window dialog = new Dialog(frame, "owned"); dialog.setSize(200, 200); dialog.setLocation(100, 100); dialog.setVisible(true); frame.setAlwaysOnTop(true); waitAWhile(); System.out.println(String.format( "frame.isAlwaysOnTop() = %s; dialog.isAlwaysOnTop() = %s", frame.isAlwaysOnTop(), dialog.isAlwaysOnTop() )); frame.dispose(); dialog.dispose(); waitAWhile(); } private static void waitAWhile() { try { Thread.sleep(2000); } catch (InterruptedException e) { e.printStackTrace(); } } } Expected output: frame.isAlwaysOnTop() = true; dialog.isAlwaysOnTop() = true frame.isAlwaysOnTop() = true; dialog.isAlwaysOnTop() = true Actual output: frame.isAlwaysOnTop() = true; dialog.isAlwaysOnTop() = false frame.isAlwaysOnTop() = true; dialog.isAlwaysOnTop() = false
