Luc Vanlerberghe commented on SOLR-8050:
----------------------------------------
As I mentioned in the code comments, not only does TrieField.createField cannot
make sense of the output of Date.toString() as opposed to a correctly formed
UTC date/time string (like "1986-01-01T00:00:00Z"), but the value the Date
object contains depends on the locale the test is run in, so there must be an
error even earlier in the update logic while decoding the values in the Lucene
Document...
> Partial update on document with multivalued date field fails

> Key: SOLR-8050
> URL: https://issues.apache.org/jira/browse/SOLR-8050
> Project: Solr
> Issue Type: Bug

> When updating a document with multivalued date field Solr throws a exception
> like: org.apache.solr.common.SolrException: Invalid Date String:'Mon Sep
> 14 01:48:38 CEST 2015'
> even if the update document doesn't contain any datefield.
> See following code snippet to reproduce
> 1. create a doc with multivalued date field (here dynamic field _dts)
> SolrInputDocument doc = new SolrInputDocument();
> String id = Long.toString(System.currentTimeMillis());
> System.out.println("testUpdate: adding test document to solr ID=" +
> id);
> doc.addField(CollectionSchema.id.name(), id);
> doc.addField(CollectionSchema.title.name(), "Lorem ipsum");
> doc.addField(CollectionSchema.host_s.name(), "yacy.net");
> doc.addField(CollectionSchema.text_t.name(), "Lorem ipsum dolor sit
> amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut
> labore et dolore magna aliqua.");
> doc.addField(CollectionSchema.dates_in_content_dts.name(), new
> Date());
> solr.add(doc);
> solr.commit(true);
> 2. update any field on this doc via partial update
> SolrInputDocument sid = new SolrInputDocument();
> sid.addField(CollectionSchema.id.name(),
> doc.getFieldValue(CollectionSchema.id.name()));
> sid.addField(CollectionSchema.host_s.name(), "yacy.yacy");
> solr.update(sid);
> solr.commit(true);
> Result
