Current implementation of Jcov does not generate coverage data for the
unqualified named while '-savebefore' and '-saveafter' instrumenter
options is used.

Jcov User Guide reads in section "B.2.3 Shared Instrumenter Options":
"The method name can be qualified as well as non-qualified. If it is
qualified, then the class file is searched for a method of a particular
class. If not, then any method with the specified name will match."

To reproduce this bug please run the following example using script
below (this script compiles the sources, run test class using dynamic
instrumenter, and finally, tryes to dump coverage datafile):
-------------------------- source begin ------------------------------
class a {

    public static void foo(){
        System.out.println("a.foo");
    }
}
public class test { // +

    public static void main (String[] args) {

        a.foo();
        System.out.println("----------");
        System.exit(0);
    }
}
-------------------------- source end --------------------------------
-------------------------- script begin ------------------------------
