[jira] [Created] (AVRO-1544) Union of enum and null can result in
NPE on validate if null is not first
Matthew Hayes created AVRO-1544:
-----------------------------------
Summary: Union of enum and null can result in NPE on validate if null is not first
Key: AVRO-1544
URL: https://issues.apache.org/jira/browse/AVRO-1544
Project: Avro
Issue Type: Bug
Components: java
Affects Versions: 1.7.6
Reporter: Matthew Hayes
The ENUM case in validate is missing a null check for datum:
{code}
case ENUM:
return schema.getEnumSymbols().contains(datum.toString());
{code}
This leads to a surprising error where a NPE is thrown for a union of enum and null when the enum is first in the union. If null is first it works. The fix is a simple. I'm creating a patch that adds the fix and a unit test for this case.
