| I noticed that this interruption error is not that exceptional; essentially it might happen at any time one stops the application. Sure it might mean there's some data loss, so we should warn about this but I'd resort to a traditional WARN in the logs rather than the whole stacktrace. Details:
method org.hibernate.search.elasticsearch.processor.impl.BatchingSharedElasticsearchWorkOrchestrator.submit(Iterable<ElasticsearchWork<?>>) Causes expceptions like:
