> Affects Versions: V2 2.0.6, V2 2.0.7
> Environment: OS- Windows 10, Java J2EE, Eclipse
> Reporter: Vinod Kannur
> Priority: Major

>
> The accept language for 1q and 2q is not supported in Olingo.
> Please refer SAP documentation

> The batch request contains Accept Language <b> en-US-x-sappsd </b>
> Content-Type: application/http
> Content-Transfer-Encoding: binary
> GET UserSettingsSet HTTP/1.1
> sap-contextid-accept: header
> Accept: application/json
> Accept-Language: en-US-x-sappsd
> DataServiceVersion: 2.0
> MaxDataServiceVersion: 2.0
> sap-cancel-on-close: true
> I debugged and found that AcceptParser class would check the language
> against the REGEX which fails and throws an exception.
> public List<String> parseAcceptableLanguages() throws BatchException {
> return parseQualifiedHeader(acceptLanguageHeaderValues,
> REG_EX_ACCEPT_LANGUAGES_WITH_Q_FACTOR,
> BatchException.INVALID_ACCEPT_LANGUAGE_HEADER);
> }
> We use pom version 2.0.6 for Olingo in our productive code and I also tried
> in 2.0.7 version, which gives the same error.

> private static final Pattern REG_EX_ACCEPT_LANGUAGES = Pattern
> .compile("((?:(?:[a-z]{1,8})|(?:\\*))\\-?(?:[a-zA-Z]{1,8})?)");
> Since 1q and 2q are valid intermediate SAP languages which is used for
> translation, batch request should accept those languages.
> Thanks,
