Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate Search ( https://hibernate.atlassian.net/browse/HSEARCH?atlOrigin=eyJpIjoiMzVjZWU4... ) / Bug ( https://hibernate.atlassian.net/browse/HSEARCH-3869?atlOrigin=eyJpIjoiMzV... ) HSEARCH-3869 ( https://hibernate.atlassian.net/browse/HSEARCH-3869?atlOrigin=eyJpIjoiMzV... ) java.lang.IndexOutOfBoundsException when an Elasticsearch bulk work fails ( https://hibernate.atlassian.net/browse/HSEARCH-3869?atlOrigin=eyJpIjoiMzV... ) Issue Type: Bug Assignee: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Components: backend-elasticsearch Created: 25/Mar/2020 05:49 AM Fix Versions: 6.0.0.Beta-backlog-high-priority Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) It looks like the class org.hibernate.search.backend.elasticsearch.work.impl.BulkWork assumes the bulk work always succeeds, leading to the creation of an empty list of result items when it fails. Consequently, if a bulk work fails, result extraction will try to access a result item that doesn't exist and trigger an IndexOutOfBoundsException.
