I wanted to use a protected member of TextArea class and so I derived it to
a new class. Even if I give no implementation to that class and if I just
create object of new derived class, after typing some characters in the
textarea, I am getting an exception whose core dump is as follows. Please
suggest me why such errors come and how to come out of it.

CODE:

TextArea t=new TextArea(20,40)
{
/*protected void processKeyEvent(KeyEvent k)
{
System.out.println("Testing:"+k);
System.exit(0);
super.processKeyEvent(k);
}*/
};



ERROR LOG:
