[hibernate-issues] [Hibernate-JIRA] Commented: (HSEARCH-309) PurgeAllLuceneWork duplicates in work queue

PurgeAllLuceneWork duplicates in work queue ------------------------------------------- Key: HSEARCH-309 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-309 Project: Hibernate Search Issue Type: Bug Components: engine Affects Versions: 3.1.0.CR1 Reporter: Sanne Grinovero Assignee: Hardy Ferentschik Fix For: 3.1.0 when using purgeAll( typeA ); you get two works to purge typeA in the queue, +1 for each subclass. The problem is caused by the presence of each type in the set of it's subtypes in DocumentBuilderContainedEntity.subclasses I tried having the typeA removed from the subclasses set, but this breaks many other features (junit told). It appears some other code is relying on the fact that this set has to contain the super class too; this looks strange? so the easy fix would be to change the current purgeAll() to not purge on the root entity too, as doing it on subclasses is enough; but it actually feels to me this is the only correct method, and we should check other usages. I've seen this affect only purgeAll but could be more critical, so priority must be investigated.
