It gives this error,

package org.jenkinsci.plugins.scoverage;

Here's a mini test class to replicate the problem, the replaceAll uses Reggex pattern matching and it's causing issues when confronted with \m

public class test {
public static void main(String args[]){
String line = "";
String pattern = "scoverage-report\com\nephila\attribution\common\mail";
String pete = line.replaceAll("href=" + pattern, "href=");
}}
