Using string values such as "\1\123" anywhere in your program causes emma to instrument code incorrectly. Here is the simplest program that I was able to use to trigger this error:
package com.emmabugs;
public class One_OneTwoThree {
public static void main(String[] s) {
System.err.println("\1\123");
}
}
When you run this program like this
java -cp c:\emma\emma.jar emmarun -merge n -raw -cp . com.emmabugs.One_OneTwoThree
you get the stack trace below (note the '☺' "face" character in the method name)
