Hi all,

When running my test suite, I get the following error at the end:
Code:
org.hibernate.HibernateException: could not destruct listeners
   at org.hibernate.event.EventListeners.destroyListeners(EventListeners.java:226)
   at org.hibernate.impl.SessionFactoryImpl.close(SessionFactoryImpl.java:983)
   ...
Caused by: java.util.ConcurrentModificationException
   at java.util.WeakHashMap$HashIterator.nextEntry(WeakHashMap.java:762)
   at java.util.WeakHashMap$EntryIterator.next(WeakHashMap.java:801)
   at java.util.WeakHashMap$EntryIterator.next(WeakHashMap.java:799)
   at org.hibernate.search.event.ContextHolder.removeSearchFactoryFromCache(ContextHolder.java:71)
   at org.hibernate.search.event.FullTextIndexEventListener.temptativeContextCleaning(FullTextIndexEventListener.java:190)
   at org.hibernate.search.event.FullTextIndexEventListener.cleanup(FullTextIndexEventListener.java:183)
   at org.hibernate.event.EventListeners$2.processListener(EventListeners.java:219)
   at org.hibernate.event.EventListeners.processListeners(EventListeners.java:181)
   at org.hibernate.event.EventListeners.destroyListeners(EventListeners.java:215)
   ... 21 more

I tried by adding synchonized to my method which closes the session but without success!

Anyone has an idea?

Regards,
Matti

Hi Matti,

can you post which testcode you are trying to execute? Is this some sort of base class for your application test suite?

Hi Hardy,

I have got a complex test suite so I need a little bit more time to find which part of the test suite goes in this state, this exception)

Regards,
Matti

Sure, first step is to isolate the problem :) Let us know when you know more.

Hi Matti,
I guess you're running your tests in parallel (testNG ?) and each test is creating/destroying the SessionFactory ?
