Buggy source:

Fixed version (ground truth):
@Override public void execute(AdminCommandContext context){
  ActionReport report=context.getActionReport();
  if (serviceName == null) {
    report.setMessage(localStrings.getLocalString("String_Node_Str","String_Node_Str"));
    report.setActionExitCode(ActionReport.ExitCode.FAILURE);
    return;
  }
  if (target != null) {
    Config newConfig=getConfigForName(target,habitat,domain);
    if (newConfig != null) {
      config=newConfig;
    }
    if (config == null) {
      report.setMessage(localStrings.getLocalString("String_Node_Str","String_Node_Str"));
      report.setActionExitCode(ActionReport.ExitCode.FAILURE);
      return;
    }
  }
  String className=ConfigModularityUtils.convertConfigElementNameToClassName(serviceName);
  Class configBeanType=ConfigModularityUtils.getClassFor(serviceName,habitat);
  if (configBeanType == null) {
    String msg=localStrings.getLocalString("String_Node_Str",DEFAULT_FORMAT,className,serviceName);
    report.setActionExitCode(ActionReport.ExitCode.FAILURE);
    report.setMessage(msg);
    return;
  }
  try {
    String serviceDefaultConfig=getActiveConfigFor(configBeanType,habitat);
    if (serviceDefaultConfig != null) {
      report.setMessage(serviceDefaultConfig);
      report.setActionExitCode(ActionReport.ExitCode.SUCCESS);
    }
  }
 catch (  Exception e) {
    String msg=localStrings.getLocalString("String_Node_Str",DEFAULT_FORMAT,serviceName,target,e.getMessage());
    LOG.log(Level.INFO,msg,e);
    report.setActionExitCode(ActionReport.ExitCode.FAILURE);
