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

[Sanne Grinovero]

I could reproduce the same problem by just running the Hibernate
Search testsuite, from master just changing the hibernate-core
dependency from 4.1.6 to 4.1.7

The failing test is
org.hibernate.search.test.embedded.EmbeddedTest

in the "hibernate-search-orm" Maven module, and reproduces exactly the
same stacktrace as reported by Guillaume.

In this case we are in a "before transaction completion" phase,
iterating over a previously non-initialized collection.

As you say, it's not finding the CollectionEntry; it would be very
nice if you could review your patch using this test to debug?
