Hello, and happy new year,

I am getting closer to the first version of a Kafka-Source for the Java
Context.

But, I am not able to "expose" the *readFromKafkaTopic()* Function I have
added.
Here is what I get after building the new distribution in my branch:

Here is the code I added to JavaPlanBuilder.scala:

Here is how I intent to test the new function with WordCount example
outside the Apache Wayang code repository:

Although I point my app project to the freshly built distribution, I do not
get access to the new function outside the Apache Wayang project, which is
an indicator for a problem in my understanding. Maybe this is due to my lag
of Scala details, or I do miss an important component in the Wayang
structure.

I also added a test but this hangs in the moment when the Kafka client
starts subscribing to the topic, before we pull data. This second issue has
been reproduced and I am on my way finding a solution for this test
problem, but regarding visibility of the function in JavaPlanBuilder I
would be happy for any hint which helps to move on.

Best wishes,
Mirko
