exception in initializer error in java when using Netbeans

Question

I am using Netbeans. I did some things with bindings and now whenever I start my program, before it even initializes the form, it gives me an error

The exception in thread main is occuring before the form is even an initialized object yet. The form is not even an object yet. Every line in my main() causes an exception. Random stuff. I don't understand it at all.

Here is the error.

    Exception in thread "main" java.lang.ExceptionInInitializerError

OBD2nerForm line 731 is bindingGroup.bind(); sometimes it errors out on pack();

the exception in main() does not even seem relevant because it occurs as soon as the program is run and every time I comment out a line it jumps to the next

        public void actionPerformed(ActionEvent evt) {
            jFormattedTextField2ActionPerformed(evt);
        }
    });

    jLabel9.setFont(new Font("DejaVu Sans", 0, 14));
    jLabel9.setText("FFFFFFFFFFFFFFFFFFFF");

Help, I do not understand. What information do you need from me?

Edit: It seems to all be code which I cannot touch. I should probably add that this started with Netbeans adding about 200 invalid imports import jCheckbox1 which I deleted.

Wherever there is errors or exceptions in static blocks, this exception will be thrown. To get the cause of this exception simply use Throwable.getCause() to know what is wrong.

Make sure the project does not have any errors. Delete the project from workspace(make the workspace a different directory from the git folder) and import again.
