-------------------------------------------
Summary: SolrJ DocumentObjectBinder.toSolrInputDocument null
handling
Key: SOLR-15112
URL: https://issues.apache.org/jira/browse/SOLR-15112
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: SolrJ
Affects Versions: 8.7
Reporter: Alessandro Benedetti
Attachments: Screenshot 2021-01-27 at 16.07.13.png
Currently the:
org.apache.solr.client.solrj.beans.DocumentObjectBinder#toSolrInputDocument
method doesn't handle nulls in java objects very well.
Even if the field is null in the Java Object, the binder adds the field(with
the null value) to the SolrInputDocument.
This may cause issues down the line, for example using UpdateRequestProcessors
such as the UUIDUpdateProcessorFactory (which doesn't check the value of the
field, but it just checks if a field is present)
The proposal here is to make the binder NOT add null fields to the
SolrInputDocument.
Any objection is welcome
