> Project: CXF
> Issue Type: Bug
> Affects Versions: 3.2.7
> Reporter: Levi Miller

>
> OAuthClientUtils.getAccessToken hides the response error if the error message
> contains a comma.
> The root cause of this is that OAuthJSONProvider.readJSONResponse uses
> String.split(",") to parse the json string, which throws
> {code:java}
> java.lang.StringIndexOutOfBoundsException: String index out of range: -1{code}
> if there are unexpected commas.
>
> Stack trace:
> {code:java}
> java.lang.StringIndexOutOfBoundsException: String index out of range: -1
> at java.lang.String.substring(Unknown Source)

> response.getEntity() json string:

> {"error":"invalid_client","error_description":"Client authentication failed
> due to unknown client, no client authentication included, or unsupported
> authentication method."}{code}
