Static Instrumenter called with '-stats' flag does not generate expected statist

Name: dkR10031 Date: 06/19/2003



The following documented feature described in section
"B.2.1 Static Instrumenter" of the Jcov User Guide:
"-stats: Print statistics to stdout. Number of methods, number of Constant
Pool elements before and after instrumentation, calculated total number of
JCov items in the input class file."

However, current Jcov implementation does not generate any statistics.
To reproduce this bug please execute the following example using by the
script below. This script compile the source and instrument class
using Static Instrumenter which is called with the '-stats' option:
-------------------------- test.java source begin --------------------
public class test {

    public static void main(String[] args) {

        System.out.println("-----------");
        java.lang.System.exit(0);
    }
-------------------------- test.java source end ----------------------
-------------------------- script begin ------------------------------
