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.
