Cannot set a breakpoint condition on an exception breakpoint

Hi,

What I am trying to do is to set an exception breakpoint targeted to one of my exceptions but suspend only when the message of the exception has a certain value. This exception overrides the constructors properly (autogenerated by IntelliJ). I am throwing the exception with the appropriate message.

I have enabled the condition check and put

this.getMessage() != null && this.getMessage().equals("oh my god!")

What happens is that when the exception is raised and the breakpoint activated, the following error is shown:

Here it is MyException code:

public class MyException extends RuntimeException{
    public MyException() {
        super();
    }

    public MyException(String message) {
        super(message);
    }

    public MyException(String message, Throwable cause) {
        super(message, cause);
    }

    public MyException(Throwable cause) {
        super(cause);
    }

    protected MyException(String message, Throwable cause, boolean enableSuppression, boolean writableStackTrace) {
        super(message, cause, enableSuppression, writableStackTrace);
    }
}

And I am raising the exception like

throw new MyException("oh my god!");

I am using
