> in current Encoder implementation, if given input is null, an NPE would be
> thrown
> The scenario would be, consider an Entity which key is allowed to be null in
> Edmx, thus, the data retrieved in data source would be a HashMap only with
> non-null value, when createEntryKey<-createSelfLink, we generate the key
> representation from the given data, some of the key would be null and passed
> to Encoder, which would throw NullPointerException and skip the check of its
> corresponding facets
> if (value == null) {
> if (facets == null || facets.isNullable() == null ||
> facets.isNullable()) {
> return null;
> } else {
> throw new
> EdmSimpleTypeException(EdmSimpleTypeException.VALUE_NULL_NOT_ALLOWED);
> }
> }
> A pull request has been created aim to fix it at
> https://github.com/apache/olingo-odata2/pull/14
