Sriharsha Chintalapani commented on KAFKA-1871:
-----------------------------------------------

[~igor.quickblox] is the serializer.class doesn't exist? if so you should get an exception like this
java.lang.ClassNotFoundException: main.java.com.services.kafka.MessageEntityToJsonSerializer
	at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
	at java.net.URLClassLoader$1.run(URLClassLoader.java:355)
