SASL support in WSO2 Stream Processor / Siddhi - ssl

Question

Qs (1) Does Siddhi application support connecting to Kafka using SASL_SSL protocol with PLAIN as SASL Mechanism.
Qs (2) If not what SASL options are available. I am using WSO2 Streaming Processor 4.4.
Below is a simple program that's expected to read from a Kafka topic and write the content as is on server console.
Note-1: The connections establishes just fine (Deployment on worker node is also successful). But nothing reflected on console.
Note:2: The program runs just fine if connected to a non secure Kafka cluster (I remove the optional.configuration and change the bootstrap servers value appropriately)
#App:name("SKAppOne")
#source(
type='kafka',
topic.list='skapp1',
group.id='g1',
partition.no.list='0',
threading.option='single.thread',
bootstrap.servers='**KAFKABROKERIP:KAFKABROKERPORT**',
optional.configuration=
***"sasl.mechanism:PLAIN,security.protocol:SASL_SSL,***

#map(type='json'))
define stream InputStreamFromSecureKafka (name string, location string);
