In DTO, validation rule is like this:

@NotEmpty
private List<String> stringListData;

In TestCase, this is true, violation count = 1

List<String> stringListData = null;
stringListDto.setStringListData(stringListData);

Set<ConstraintViolation<StringListDto>> constraintViolations = validator
.validate(stringListDto);
logger.error("violation count: {}", constraintViolations.size());
Assert.assertEquals(1, constraintViolations.size());

But, this has error, NoSuchMethodError occures:

List<String> stringListData = new ArrayList<String>();
stringListDto.setStringListData(stringListData);
Set<ConstraintViolation<StringListDto>> constraintViolations = validator
.validate(stringListDto);
logger.error("violation count: {}", constraintViolations.size());
Assert.assertEquals(1, constraintViolations.size());

I expect violation count is 1, because stringListData is empty.
But NoSuchMethodError occures.
