first of all, i'm not goot at english.. if you can't understant what i'm saying .. just loot at source code and error message below~ 
thank you.

== Situation ==
I'm using avro-quick-start sample code using github...
It works fine with java-to-java, python-to-python, java-to-python but It not working... java-to-python..

I think it caused by difference of data type between java and mac-python-64x
