http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-525
Project: Hibernate Search
Issue Type: Bug
Affects Versions: 3.2.0.CR1, 3.1.1.GA
Environment: Ubuntu 9.10, java version "1.6.0_0"
OpenJDK Runtime Environment (IcedTea6 1.6.1) (6b16-1.6.1-3ubuntu3)
OpenJDK Server VM (build 14.0-b16, mixed mode),
mysql Ver 14.14 Distrib 5.1.37, for debian-linux-gnu (i486) using EditLine wrapper
Reporter: ddbattlefield2142
Attachments: HibernateSearchBugReport.tgz
Write a class with one main method. Call a method which loads one entity (preexisting
data) and tries to index it. The code runs fine and the main thread returns but the
application hangs. Some thread spawned by hibernate is keeping the application from
exiting. You would need to press control + C to exit the application.
Please refer to README in the attachment for a list of dependencies I am using and the
running instructions.

-------------------------------------------
In the title of this bug when I say "some other thread spawned", I mean some
other thread is spawned by either some code in hibernate jars (most likely hiberante
search jar) or one of the dependencies. A list of open files obtained after main thread
terminates shows a file handle open to index file(s).

Sanne Grinovero resolved HSEARCH-525.
-------------------------------------
Resolution: Rejected
Hi, this is very simple: you need to close the sessionfactory. You always need to, not
just when using Search, usually you don't notice but it could lead to problems
anyway.
SESSION_FACTORY.close();

ddbattlefield2142 commented on HSEARCH-525:
-------------------------------------------
Not closing the SessionFactory doesn't stop application from exiting if you remove the
FullTextSession.index(object) call. Hence, that could not be the problem. I wrote numerous
code examples for Hibernate (core, not search) and I never closed SessionFactory but I
never ran into that problem before. As I said, just remove the
FullTextSession.index(object) call, don't close SessionFactory and you won't see
that problem. Hence, there is some other reason behind this behavior.

-------------------------------------------
Sanne Grinovero: I see that what you suggested works. Putting that in conjunction with my
previous comment (Not closing the SessionFactory .... ) doesn't explain the cause
though; at least not to me. Could you point out the cause?

Sanne Grinovero commented on HSEARCH-525:
-----------------------------------------
sure, the cause is exactly what you guessed in your first comment. the Search engine is
spawning some helper threads which are needed to achieve top performance; while you
usually don't notice problems when "forgetting" to close the SessionFactory,
there still might be problems like leaked resources. The "close()" method was
not added for Search alone, it exists since long time. I guess you never noticed it as
especially unit tests can't possibly test anything after they're finished ;)
I don't know exactly what could happen or which other plugins and listeners could rely
on this (caches, connection pools, whatever you're using), but closing it is for sure
the correct way to go.
