A DESCRIPTION OF THE PROBLEM :
We first try to call String var1 = (new XEvent()).toString(); This can lead to the Hotspot report Java. Lang. ArrayIndexOutOfBoundsException.
But when before this increase call new JEditorPane. JEditorPaneAccessibleHypertextSupport (new JEditorPane ()); Can lead to AWTError Hotspot8 report, while ArrayIndexOutOfBoundsException Hotspot11 will still be report.
Here is the code involved, we provide the Jimple code for reproducing the bug.

import javax.swing.JEditorPane;
import sun.awt.X11.XEvent;

public class test {
    public static void main(String[] var0) {
        new JEditorPane.JEditorPaneAccessibleHypertextSupport(new JEditorPane());
        String var1 = (new XEvent()).toString();
    }
}


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
ArrayIndexOutOfBoundsException
ACTUAL -
AWTError
