Kiran Kumar Dontam created SOLR-6815: ----------------------------------------
Summary: Issue with Collections in field value while indexing a document. Key: SOLR-6815 URL: https://issues.apache.org/jira/browse/SOLR-6815 Project: Solr Issue Type: Bug Components: clients - java Affects Versions: 4.9 Reporter: Kiran Kumar Dontam Priority: Minor Issue with {{SolrInputDocument.addField()}} method. If this method is called for the first time for a field, it will call {{setField}} method, which calls {{SolrInputField.setValue}}. Assume that the value is a Collection in this flow. The value's reference is added to the field in the doc. If we add another value to the same field (using {{addField}}), it will be added to the original collection. This is incorrect because we are modifying user's original collection. This will break in the following cases: 1. If the original collection is unmodifiable. This will throw {{UnsupportedOperationException}} while adding 2nd value. 2. If the user wants to add the same value (Collection) to different fields, those fields may get corrupted. Adding more values to one fields will add them to other fields as well. (This is how I found the issue). One solution: In {{SolrInputField.setValue}} we can always create a new Collection (ArrayList) if the incoming value is a Collection. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
