Sometimes, in my platform application, someone seems to keep triggering this:
java.lang.NullPointerException

at java.awt.EventDispatchThread.run(Unknown Source) 

Which occurs continuously. Since we send a crash report everytime a severe log entry with an exception comes through (this is a beta), it spams the crash report system.

I don't know how they are doing it, but after looking at the source code:
        private static synchronized ExceptionFlasher notify(String summary, ImageIcon icon) {
            if (flash == null) {
                flash = new ExceptionFlasher();
            } else {
                flash.timer.restart();
                flash.note.clear();
            }
            JComponent detailsPanel = getDetailsPanel(summary);
            JComponent bubblePanel = getDetailsPanel(summary);

            flash.note = NotificationDisplayer.getDefault().notify(
                    NbBundle.getMessage(NotifyExcPanel.class, "NTF_ExceptionalExceptionTitle"),
                    icon, bubblePanel, detailsPanel,
                    NotificationDisplayer.Priority.SILENT, NotificationDisplayer.Category.ERROR);
            return flash;
        }

It seems like an easy fix, replace
                flash.note.clear();
with
                if (flash.note != null)
                    flash.note.clear();
Could you get this fixed please?
