Buggy source:
@Override public boolean process(String type,String message,Object object){
  if (type.equals(CompleteApplicationSignUpsEvent.class.getName())) {
    CompleteApplicationSignUpsEvent event=(CompleteApplicationSignUpsEvent)MessagingUtil.jsonToObject(message,CompleteApplicationSignUpsEvent.class);
    if (event == null) {
      log.error("String_Node_Str");
      return false;
    }
    if (!ApplicationSignUpManager.getInstance().isInitialized()) {
      try {
        ApplicationSignUpManager.acquireWriteLock();
        for (        ApplicationSignUp applicationSignUp : event.getApplicationSignUps()) {
          ApplicationSignUpManager.getInstance().addApplicationSignUp(applicationSignUp);
          if (log.isDebugEnabled()) {
            log.debug(String.format("String_Node_Str",applicationSignUp.getApplicationId(),applicationSignUp.getTenantId()));
          }
        }
        ApplicationSignUpManager.getInstance().setInitialized(true);
      }
  finally {
        ApplicationSignUpManager.releaseWriteLock();
      }
    }
    notifyEventListeners(event);
    return true;
  }
 else   if (nextProcessor != null) {
    return nextProcessor.process(type,message,object);
  }
 else {
    throw new RuntimeException(String.format("String_Node_Str" + "String_Node_Str",type,message));
  }
}

Fixed version (ground truth):
@Override public boolean process(String type,String message,Object object){
  if (type.equals(CompleteApplicationSignUpsEvent.class.getName())) {
    CompleteApplicationSignUpsEvent event=(CompleteApplicationSignUpsEvent)MessagingUtil.jsonToObject(message,CompleteApplicationSignUpsEvent.class);
    if (event == null) {
      log.error("String_Node_Str");
      return false;
    }
    if (!ApplicationSignUpManager.getInstance().isInitialized()) {
      try {
        ApplicationSignUpManager.acquireWriteLock();
        for (        ApplicationSignUp applicationSignUp : event.getApplicationSignUps()) {
          ApplicationSignUpManager.getInstance().addApplicationSignUp(applicationSignUp);
          if (log.isDebugEnabled()) {
            log.debug(String.format("String_Node_Str",applicationSignUp.getApplicationId(),applicationSignUp.getTenantId()));
          }
        }
        ApplicationSignUpManager.getInstance().setInitialized(true);
        log.info("String_Node_Str");
      }
  finally {
        ApplicationSignUpManager.releaseWriteLock();
      }
    }
    if (!DomainMappingManager.getInstance().isInitialized()) {
      try {
        DomainMappingManager.acquireWriteLock();
        for (        ApplicationSignUp applicationSignUp : event.getApplicationSignUps()) {
          DomainMappingManager.getInstance().addDomainMappings(Arrays.asList(applicationSignUp.getDomainMappings()));
        }
        DomainMappingManager.getInstance().setInitialized(true);
        log.info("String_Node_Str");
      }
  finally {
        DomainMappingManager.releaseWriteLock();
      }
    }
    notifyEventListeners(event);
    return true;
