Fixed version (ground truth):

    detailsStringBuilder.append("String_Node_Str");
    for (    String fileID : resourceList) {
      noteStringBuilder.append(fileID + "String_Node_Str");
    }
    noteStringBuilder.setLength(noteStringBuilder.length() - 2);
    detailsStringBuilder.append(details);
    detailsStringBuilder.append("String_Node_Str");
    noteStringBuilder.append(detailsStringBuilder);
    if (pluginState == PluginState.SUCCESS)     noteStringBuilder.setLength(0);
    if (pluginState == PluginState.FAILURE || (pluginState == PluginState.PARTIAL_SUCCESS && hasPartialSuccessOnOutcome == false)) {
      pluginState=PluginState.FAILURE;
      noteStringBuilder.setLength(0);
    }
    outcomeDetails=noteStringBuilder.toString();
  }
 catch (  Throwable e) {
