Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *commented* on HSEARCH-3900 ( https://hibernate.atlassian.net/browse/HSEARCH-3900?atlOrigin=eyJpIjoiMTZ... ) Re: drop-and-create strategy is not working at app. startup when "hibernate.search.autoregister_listeners" is set to false. And if true, startup index creation thread are not released, sending the app in out of memory. ( https://hibernate.atlassian.net/browse/HSEARCH-3900?atlOrigin=eyJpIjoiMTZ... ) I do not know for sure, as I'm not involved in the WebSphere project and personally have never used it. IBM support or the WebSphere community may know better. That being said, I am not aware of any incompatibility. As long as Hibernate ORM and Lucene work correctly in Websphere, Hibernate Search should theoretically work fine as well. Hibernate Search does not rely on many Java EE features, and can run on Java SE.
