    Description

      You can reproduce the bug by adding the code into the AvroDeserializationSchemaTest.
      The code follows

      @Test
	public void testSpecificRecord2() throws Exception {
		DeserializationSchema<Address> deserializer = AvroDeserializationSchema.forSpecific(Address.class);

		Address deserializedAddress = deserializer.deserialize(null);
		assertEquals(null, deserializedAddress);
	}

      Exception stack:
