Dear Support,
The server is working just fine and clients are able to connect and can communicate to each other, but it’s throwing an exception error in service logs.
Please refer to the attached service logs.
Thank you.
Looks like a JDK bug:
Bug ID: JDK-6607186 ClassCastException casting to sun.awt.Win32GraphicsEnvironment
Thanks, CSH. seem I just gonna ignore it since all client’s comm. are fine.
