JDK-8155740 - [macosx] robot.keyPress and robot.keyRelease do not generate key event for Alt-Graph key VK_ALT_GRAPH.
Description
The robot does not properly set/use key modifiers after JDK-8155740.

The issue became critical when one test presses/unpresses the META/SHIFT/etc keys, but the robot generate only the press event, this cause all possible weird results for the later tests.

For example every tests runs on macOS open lots of utility windows of terminal becaouse one test press Command key, and one another test try to press different keys which apparently became shortcuts(CMD+XXX), example one of the shortcut is CMD+H to hide the current test window(terminal became the focus window), and second is CMD+I to open utility window of the terminal.
Comments
To reproduce this bug, it is necessary to run these 3 tests in a row: java/awt/event/KeyEvent/KeyChar/KeyCharTest.java java/awt/event/KeyEvent/SwallowKeyEvents/SwallowKeyEvents.java java/awt/keyboard/AllKeyCode/AllKeyCode.java

I have filed the bug to the Apple that an example on the link below does not work properly: https://developer.apple.com/documentation/coregraphics/1456564-cgeventcreatekeyboardevent?language=objc The answer is: "You have to post and give time for the event source to update to match state. Try put some delays between each CGEventPost. ...and the creation of subsequent events needs to be after those postings - the events inherit their flags at creation time." So we either need to add delays so the shift/meta key will modify the state before we will send the next event, or we can maintain the state of the "next events" itself, it is possible to set the key modifiers manually via CGEventSetFlags();
