> I ran into a bug with schema validation code that throws unexpected NullPointerException when validating a schema with enum type. The bug is present in latest version of Avro Java API.
> h4. *Schema to replicate issue:* 
> { "type": "enum", "name": "Suit", "symbols" : [null] }
> *{{Replication Steps:}}*
>  # Validate the above schema using Java API.
>  # I used avro-cli for testing but was also able to replicate with API.
>  # {{java -jar avro-cli-0.2.7.jar normalize -s ~/tmp/schema.txt}}
> *{{Exception:}}*

> {{As seen in the [code|https://github.com/apache/avro/blob/master/lang/java/avro/src/main/java/org/apache/avro/Schema.java#L1557], there is no null check on symbol which is causing this.}}
