Did not investigate any further because we can depend on Avro 1.8.1 in most 
cases. However, we would like to use Avro 1.8.2 because of AVRO-607.

Hm, interesting, it seems those lines which stuck in infinite recursion are 
submitted with AVRO-328, which was committed quite a long ago. Do you have any 
idea what could be the root cause, what has changed between the two releases 
which broke this logic?

This appears to be a bug in Avro 1.8.2. If I downgrade to Avro 1.8.1, I do not 
see this issue when validating schemas.
