I have this working in 3.8:
constraint =
validationHelper.createExplicitListConstraint(valList); //String[]
valList
dataValidation =
validationHelper.createValidation(constraint, addressList);
dataValidation.setSuppressDropDownArrow(true);
dataValidation.createPromptBox("Valid Values", prompt);
dataValidation.setShowPromptBox(true);
dataValidation.setShowErrorBox(true);
dataValidation.setErrorStyle(DataValidation.ErrorStyle.
STOP);
dataValidation.setEmptyCellAllowed(false);
dataValidation.createErrorBox("Validation Error",
validationMsg);
sheet.addValidationData(dataValidation);
