ExceptionInInitializerError

My application is an editor. Initially, the editor is hidden. It will be only opened when the new button is clicked.

When this button is clicked, this error occurred:

Unhandled event loop exception

Reason:

java.lang.ExceptionInInitializerError

May someone help me fix this error?

Thanks.
