Timo Walther updated FLINK-11727:
---------------------------------
    Description: {\{JsonRowSerializationSchema}} and 
\{{JsonRowDeserializationSchema}} use reference comparisons for more efficient 
execution, however, these do not work after serialization of the class when 
shipping it to a cluster. This error was not immediately visible as the logic 
in the else clause was also able to partially do the correct logic.  (was: 
{\{JsonRowSerializationSchema}} and \{{JsonRowDeserializationSchema}} use 
reference comparisons for more efficient execution, however, these do not work 
after serialization of the class when shipping it to a cluster. This error was 
not immediately visible as the logic in the else clause was also able to 
partially to the correct logic.)
