Error Report on Openfire Monitoring

Hello guy’s…

my office use OPENFIRE for communication internal / external.

I’ve seen in the openfire monitoring always appear error messages like this:

Exception in thread “AWT-EventQueue-0” java.lang.ClassCastException: sun.java2d.HeadlessGraphicsEnvironment cannot be cast to sun.awt.Win32GraphicsEnvironment
at sun.awt.windows.WToolkit$4.run(Unknown Source)

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

Whether there can inform me what is the error message above ?

and solutions how to fix it ?

Best Regard’s
