hibernate search 3.4.0 RC2 issue (null pointer when index)

hi,

i just upgrade lucene 3.0.3, hibernate 3.6.3/3.6.2 final (both not work) and hibernate search 3.3.0 final to the latest 3.4.0 RC2.

without any code change, i assume it can run without any problem.

however, when my code update an entity with collection (@indexEmbedded) it throws NullPointerException:

Code:

java.lang.NullPointerException
   org.hibernate.search.event.FullTextIndexEventListener.processCollectionEvent(FullTextIndexEventListener.java:242)
   org.hibernate.search.event.FullTextIndexEventListener.onPostRemoveCollection(FullTextIndexEventListener.java:226)

   org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:202)
   $Proxy38.update(Unknown Source)
..... //other code omit 

I using debugger to trace, it find out that is cause by the event object, when event object pass to onPostRemoveCollection method, the event object's collection is null, hence when running processCollectionEvent (line 242 event.getCollection() ) it throw null pointer exception.

my object is something like this :

Object A {
@indexEmbedded
ObjectB B = ...
}

Object B {
Set<ObjectC> set..
}

is that a bug, or do i missing some configuration setting (my configuration is not changing, still using same as 3.3.0)

any idea ?

Did you upgrade lucene to 3.1.0 ?

yes. i think can;t run if u not using lucene 3.1.

i think the problem occurs before lucene index the field (HS can;t find the collection in the event object since it is null).

Hi kiwionly.
thank you for the report, that's indeed a bug; just in time to be fixed before the release today (I hope still on time..).

and also, Elmer is right with this version you have to update Lucene to 3.1 as well.
