> OLingo client crashes when encountering a null value for an enum property
> -------------------------------------------------------------------------
>
> Key: OLINGO-1152
> URL: https://issues.apache.org/jira/browse/OLINGO-1152
> Project: Olingo
> Issue Type: Improvement
> Components: odata4-client
> Affects Versions: (Java) V4 4.3.0
> Reporter: Tom van Wietmarschen
> Attachments:
> 0001-OLINGO-1152-Fix-IllegalArgumentException-when-enum-p.patch
>
>
> An IllegalArgumentException is thrown when the OLingo client encounters a
> enum property that has a null value. It turns out the Property's value is set
> to "null" (a String) instead of null. Tracing back the source of the
> null-String shows
> {{org.apache.olingo.client.core.serialization.JsonDeserializer}} always
> assumes Enum values are Strings. (It calls node.asText() even on a NullNode),
> adding a isNull() check solves the issue. Patch to follow.
