private static <V> Set<ConstraintViolation<?>> doBeanValidation(V paramValue, InjectionPoint injectionPoint) {

		Class<?> base = injectionPoint.getBean().getBeanClass();
		String property = injectionPoint.getMember().getName();
		Type type = injectionPoint.getType();

		// Check if the target property in which we are injecting in our special holder/wrapper type
		// ParamValue or not. If it's the latter, pre-wrap our value (otherwise types for bean validation
		// would not match)
		Object valueToValidate = paramValue;

		if (type instanceof ParameterizedType) {
			Type propertyRawType = ((ParameterizedType) type).getRawType();
			if (propertyRawType.equals(ParamValue.class)) {
				valueToValidate = new ParamValue<>(null, null, null, paramValue);

		return (Set) getBeanValidator().validateValue(base, property, valueToValidate);

The problem is that the injectionPoint.getMember().getName() returns the bean's class name to the property instead of the parameter name, then getBeanValidator().validateValue(_) throws Invalid property path. There is no property com in entity com.cpox.view.product.ProductVersionBacking or the likes.

It does not happen if the bean does not have any properties annotated with validation constraints, because then validateValue(_) returns without doing anything.
