% cat -n badscope.java
     1 public class badscope {
     2 public static final void main(String args[])
     3 {
     4 // this line should be here
     5 try {
     6 System.out.println("hi!");
     7 } catch (Exception e) {
     8 e.printStackTrace();
     9 } finally {
    10 System.out.println("done");
    11 }
    12 }
    13 }

Compiling this using "javac -g" and 1.4 FCS generates
the following (same for 1.4.1):

% javap -c -l badscope

----------

Is the range of e really pc=15, length=27? Seems
like it is only defined inside the catch, not through
the end of main() (This is the subject of 4690242)
