AuthorizationGrant.parse with a map missing grant type throws weird exception

[Henri Mikkonen]

If the AuthorizationGrant.parse(final Map<String,List<String>> params) method is called with a map that doesn’t contain grant_type, quite weird exception is thrown.

        try {
            AuthorizationGrant.parse(new HashMap<>());
        } catch (Exception e) {
            e.printStackTrace();
        }

STDOUT:

java.lang.IllegalArgumentException: Illegal char(s) in description, see RFC 6749, section 5.2
    at com.nimbusds.oauth2.sdk.ErrorObject.<init>(ErrorObject.java:148)
    at com.nimbusds.oauth2.sdk.ErrorObject.appendDescription(ErrorObject.java:211)
    at com.nimbusds.oauth2.sdk.AuthorizationGrant.parse(AuthorizationGrant.java:113)

I’m using oauth2-oidc-sdk-8.33.jar

Thanks for the report.

That's probably due to this:

https://tools.ietf.org/html/rfc6749#section-5.2

     Values for the "error_description" parameter MUST NOT include
     characters outside the set %x20-21 / %x23-5B / %x5D-7E.

Will add a test.

Fixed in commit f8dd113 , releasing as v 8.33.1.

Happy coding!

There was a release hiccup, check out v8.33.2 instead please.
