> {{When an enum field is written with a symbol that is not one of the valid
> enum symbols configured in the schema, the code generates a NPE which turns
> into a null value message which is not extremely helpful. It would be useful
> if the message mentioned the invalid symbol and the available symbols from
> the schema.}}
> Here's a sample of the generated stack trace. More in the attachment:
> {{java.lang.NullPointerException: null value for (non-nullable) enum1 at
> record1.field1}}
> {{ ...}}
> {{Caused by: java.lang.NullPointerException}}
> {{ at org.apache.avro.Schema$EnumSchema.getEnumOrdinal(Schema.java:1118)}}
> {{...}}
