                 URL: https://jira.jboss.org/jira/browse/JBAS-7448
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Web (Tomcat) service
    Affects Versions: JBossAS-5.1.0.GA
            Reporter: Emilio Davis

As described in http://labs.jboss.com/community/wiki/HAWebSessionsviaDatabasePersistencethere there is a way to tell JBoss to store web sessions in a datasource without using the Tomcat PersistentManager but the code both in the same article and in the SVN (trunk) have the same bug:

The problem seems to be in the maskId function in org.jboss.web.tomcat.service.session.persistent.RDBMSStoreBase 



1064   private static String maskId(String realId)
1065   {
1066      if (realId == null)
1067      {
1068         return null;
1069      }
1070      else
1071      {
1072         int length = realId.length();
1073         if (length <= 8)
1074         {
1075            return realId;
1076         }
1077         StringBuilder sb = new StringBuilder(realId.substring(0, 2));
1078         sb.append("****");
1079         sb.append(sb.substring(length - 6, length));
1080         return sb.toString();
1081      }
1082   }


The line 1079 should be 

sb.append(realId.substring(length - 6, length));


I already opened a thread in the forum of tomcat intergration about this but got no response.
