-------------------------------------
Summary: ValueDeserializerWrapper throws NullPointerException when
getProducedType is invoked
Key: FLINK-21160
URL: https://issues.apache.org/jira/browse/FLINK-21160
Project: Flink
Issue Type: Bug
Components: Connectors / Kafka
Reporter: Qingsheng Ren
The variable {{deserializer}} in class {{ValueDeserializerWrapper}} won't be
instantiated until method {{deserialize()}} is invoked in runtime, so in the
job compiling stage when invoking {{getProducedType()}}, NPE will be thrown
because of referencing the uninstantiated variable {{deserializer}}.
