		assertEquals(null, deserializedAddress);
	}

{code}

Exception stack:

{code:java}
java.lang.NullPointerException
	at org.apache.flink.formats.avro.utils.MutableByteArrayInputStream.setBuffer(MutableByteArrayInputStream.java:43)
	at org.apache.flink.formats.avro.AvroDeserializationSchema.deserialize(AvroDeserializationSchema.java:131)
