Description
Instantiation of JPopupMenu in headless mode started to cause NPE since approximately JDK9b22.
This problem is not observed with JDK8u5 for example.
The following code if run with JDK9b23 with -Djava.awt.headless=true
------------------------------------------------------------
public class JPM {
public static void main(String[] args) {
new javax.swing.JPopupMenu();
}
}
------------------------------------------------------------
results in
Exception in thread "main" java.lang.NullPointerException
