      Description

      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.
