charWidth(newline) incorrectly reports a non-zero value.

A "return" character '\n' should have a width of zero, and the
JDK1.1 correctly reports this using charWidth('\n'), but
NOT JDK1.2! My application crashes under JDK1.2 because of
this. This bug may be similar to bugs 4069228, 4031360, and
4168118, but this one is more widespread: its there seemingly
independent of font.

Compile and run the following code under both JDK1.1 and JDK1.2
to see the difference:

import java.awt.*;
import java.applet.*;
import java.lang.*;

public class Bug1{
    
    public static void main(String args[]){
FontMetrics FM;
TextArea t = new TextArea(5,40);

FM = t.getFontMetrics(new Font("Dialog",Font.PLAIN,12));

System.out.println("Bug1: A java 1.2 bug in charWidth(): \n");
System.out.println("Width of \\n = "+FM.charWidth('\n'));
System.exit(0);
    }
}

For JDK1.1, the output is the expected:
Bug1: A java 1.2 bug in charWidth():

Width of \n = 0


But on windows98, the JDK1.2 output is
Bug1: A java 1.2 bug in charWidth():

Width of \n = 8


FYI, "java -version" gives
java version "1.2.2"
Classic VM (build JDK-1.2.2-W, native threads, symcjit)

"java -fullversion" gives
JAVA.EXE full version "JDK-1.2.2-W"
