STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
In jshell:
import java.awt.Robot;
var awtRobot = new Robot();
awtRobot.keyPress(java.awt.event.KeyEvent.VK_1);

ACTUAL -
Crashes the jvm

CUSTOMER SUBMITTED WORKAROUND :
The adoptOpenJDK build works as expected. The oracle openjdk build crashes

FREQUENCY : always
