[hibernate-dev] Regression after upgrade to 4.1.7.Final

[Guillaume Smet]

Hi,

We just upgraded to Hibernate 4.1.7.Final (from 4.1.6.Final) and we
have a pretty bad regression with 4.1.7 and Hibernate Search 4.1.1.

We have the following stack trace when saving an object:
Caused by: org.hibernate.HibernateException: Error while indexing in

I don't know if it's something obvious or if you need a self contained
test case to reproduce it.

I haven't created a JIRA because I don't know if it's an
incompatibility between Hibernate Search 4.1.1 and Hibernate 4.1.7 or
a real bug (either in HHH or HSEARCH).

Feel free to ping me for more information or any further action.

Thanks.
