Buggy source:
@Override public String getPermissionLimit(final Player p,final String limit){
  String result=null;
  if (mChat) {
    result=Reader.getInfo(p.getName(),InfoType.USER,p.getWorld().getName(),"String_Node_Str" + limit);
  }
  if (result == null || (result != null && result.isEmpty())) {
    final Pattern regex=Pattern.compile("String_Node_Str" + limit.toLowerCase() + "String_Node_Str");
    Map<String,PermissionAttachmentInfo> permissions=null;
    try {
      final PermissibleBase perm=ClassUtils.getPrivateField(p,"String_Node_Str");
      permissions=ClassUtils.getPrivateField(perm,"String_Node_Str");
    }

    int max=Integer.MIN_VALUE;

Fixed version (ground truth):

    Map<String,PermissionAttachmentInfo> permissions=null;
    try {
      Permissible perm=ClassUtils.getPrivateField(p,"String_Node_Str");
      try {
        permissions=ClassUtils.getPrivateField(perm,"String_Node_Str");
      }
 catch (      final NoSuchFieldException e) {
        perm=ClassUtils.getPrivateField(perm,"String_Node_Str");
