Unable to leave truststore options blank in version 1.3

[36roentgen]

Java trace indicates it thinks kafkaSslTruststore is a directory when left blank.

However I would like to note, the work around posted higher in the thread doesn't work for me except for the PLAINTEXT part only. Only method I could find to work around is to manually edit the file Kafka Producer Config.jmx and remove references to the truststore.
