Ray Chiang updated KAFKA-5802:
------------------------------
Component/s: security
> ScramServerCallbackHandler#handle should check username not being null before
> calling credentialCache.get()
> -----------------------------------------------------------------------------------------------------------
>
> Key: KAFKA-5802
> URL: https://issues.apache.org/jira/browse/KAFKA-5802
> Project: Kafka
> Issue Type: Bug
> Components: security
> Reporter: Ted Yu
> Priority: Minor
>
> {code}
> String username = null;
> for (Callback callback : callbacks) {
> if (callback instanceof NameCallback)
> username = ((NameCallback) callback).getDefaultName();
> else if (callback instanceof ScramCredentialCallback)
> ((ScramCredentialCallback)
> callback).scramCredential(credentialCache.get(username));
> {code}
> Since ConcurrentHashMap, used by CredentialCache, doesn't allow null keys, we
> should check that username is not null before calling credentialCache.get()
