NPE occurs when using Infinispan as L2 Cache
--------------------------------------------
Key: HHH-5599
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5599
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.5.6, 3.5.5
Environment: Hib 3.5.6
Infinispan 4.2.0.ALPHA2
(same thing happen with Hib 3.5.5 and IS 4.1.0.FINAL)
Reporter: Chris
Priority: Critical
Pretty much randomly or so it seems, infinispan hibernate layer will throw a NPE. It
occurs a lot when the j2EE server is started and overtime (once caches are warmer?)
diminish.
The issue comes from the PutFromLoadValidator.Java(565).The cleaned element is null and
the map.put(cleaned) fails since the key is coming from the cleaned element
(cleaned.owner).
Complete stacktraces, the first on entity loading and the later on collection loading:
Cause: java.lang.NullPointerException

For now I am masking this class with my own which essentially is a copy and paste but
added a null check before trying to put back the element.
How the big question is : Is it normal that the element can be null and it's a simple
null check that has been forgotten or the element should never be null and something
bigger is going on ?

---------------------------------------
Chris, thanks for reporting this. Had a quick look to this and not sure if you're
workaround is valid or not. I'd be very interested of getting hold of your test or
Hibernate app and how to replicate this issue cos I haven't seen it before. Any chance
you could do so?

Chris commented on HHH-5599:
----------------------------
Hi Galder,
My webapp is a rather very large and complex one, it's hard to reproduce this issue on
my dev computer but not impossible however it's pretty much random. The ramdomness
dwindle a lot as soon as you throw some concurrent load on the webapp at startup when the
caches are being warmed.
Is there some debug I can turn on that would shed some light on what is going on ? Also
with your knowledge of Infinispan, could it be usefull to code a little snippet that would
output usefull information like the cache and cache key in question when a NPE is about to
happen ? I could then insert this code to provide additional informations.
The hard thing is this thing happen really deep on the stack, it cant be really any deeper
and it's almost impossible to know what really triggered it, especially if it's a
concurrency issue somehow.
I was hoping that you would see in which scenario this would happen from the stacktrace,
maybe with the additional information I am talking about above, we will be able to sort it
out.
NPE occurs when using Infinispan as L2 Cache
--------------------------------------------
Key: HHH-5599
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5599
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.5.5, 3.5.6
Environment: Hib 3.5.6
Infinispan 4.2.0.ALPHA2
(same thing happen with Hib 3.5.5 and IS 4.1.0.FINAL)
Reporter: Chris
Assignee: Galder Zamarreno
Priority: Critical
Pretty much randomly or so it seems, infinispan hibernate layer will throw a NPE. It
occurs a lot when the j2EE server is started and overtime (once caches are warmer?)
diminish.
The issue comes from the PutFromLoadValidator.Java(565).The cleaned element is null and
the map.put(cleaned) fails since the key is coming from the cleaned element
(cleaned.owner).
Complete stacktraces, the first on entity loading and the later on collection loading:

For now I am masking this class with my own which essentially is a copy and paste but
added a null check before trying to put back the element.
How the big question is : Is it normal that the element can be null and it's a simple
null check that has been forgotten or the element should never be null and something
bigger is going on ?

Galder Zamarreno commented on HHH-5599:
---------------------------------------
Chris, the code where this is coming from is relatively complex and so it's not a
straightforward thing to figure out what the cause is, and whether the cause is a valid
one and should protect against, or whether instead is a bug somewhere else in the code.
Unfortunately, there's not much logging in this area, so I don't think it'd
help much unless it can clarify the following doubt I have:
Are you accessing Hibernate within transactions or not? If you're using transactions,
what type of transactions and which is the transaction manager that you're using? Can
you attach your hibernate configuration file?
Also, if you're using transactions, I'd like to understand the flow of
transactions and whether a particular transaction can be accessed by different threads.
Based on what I've seen, a particular key can either be cleaned up:
a) This is materially impossible but by the same thread twice a row. I can't see how
this can happen cos the same thread, concurrently would need to call one of the operations
that can cleanup the pending map.
b) By the same transaction twice in a row. Now, if your transactions can span multiple
threads, two parts of the same transaction might be calling clean up of the same key and
since their transaction would be the same, this could be a possibility.

The changes to pendingPuts.remove are not directly related to this issue; just I think
they are the right thing to do.
What's happening is a race to the PendingPutMap lock between a thread cleaning an
"outdated" pending put and either another thread doing the same, or the put
itself coming in and cleaning it. For the losing thread, PendingPut cleaned =
map.remove(toClean.owner); is returning null, since the winning thread already did the
removal.

For now I am masking this class with my own which essentially is a copy and paste but
added a null check before trying to put back the element.
How the big question is : Is it normal that the element can be null and it's a simple
null check that has been forgotten or the element should never be null and something
bigger is going on ?

New subject: [Hibernate-JIRA] Resolved: (HHH-5599) NPE occurs when using Infinispan as L2 Cache
[
http://opensource.atlassian.com/projects/hibernate/browse/HHH-5599?page=c...
]
Galder Zamarreno resolved HHH-5599.
-----------------------------------
Resolution: Fixed
Fix Version/s: 4.0.0.Alpha1
3.x
3.6.1
Fixed in 3.5.x, 3.6.x and trunk branches.
NPE occurs when using Infinispan as L2 Cache
--------------------------------------------
Key: HHH-5599
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5599
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.5.5, 3.5.6
Environment: Hib 3.5.6
Infinispan 4.2.0.ALPHA2
(same thing happen with Hib 3.5.5 and IS 4.1.0.FINAL)
Reporter: Chris
Assignee: Galder Zamarreno
Priority: Critical
Fix For: 3.6.1, 3.x, 4.0.0.Alpha1
Pretty much randomly or so it seems, infinispan hibernate layer will throw a NPE. It
occurs a lot when the j2EE server is started and overtime (once caches are warmer?)
diminish.
The issue comes from the PutFromLoadValidator.Java(565).The cleaned element is null and
the map.put(cleaned) fails since the key is coming from the cleaned element
(cleaned.owner).
Complete stacktraces, the first on entity loading and the later on collection loading:
Cause: java.lang.NullPointerException

For now I am masking this class with my own which essentially is a copy and paste but
added a null check before trying to put back the element.
How the big question is : Is it normal that the element can be null and it's a simple
null check that has been forgotten or the element should never be null and something
bigger is going on ?

New subject: [Hibernate-JIRA] Reopened: (HHH-5599) NPE occurs when using Infinispan as L2 Cache
[

Steve Ebersole reopened HHH-5599:
---------------------------------
NPE occurs when using Infinispan as L2 Cache
--------------------------------------------
Key: HHH-5599
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5599
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.5.5, 3.5.6
Environment: Hib 3.5.6
Infinispan 4.2.0.ALPHA2
(same thing happen with Hib 3.5.5 and IS 4.1.0.FINAL)
Reporter: Chris
Assignee: Galder Zamarreno
Priority: Critical
Fix For: 3.6.1, 4.0.0.Alpha1
Pretty much randomly or so it seems, infinispan hibernate layer will throw a NPE. It
occurs a lot when the j2EE server is started and overtime (once caches are warmer?)
diminish.
The issue comes from the PutFromLoadValidator.Java(565).The cleaned element is null and
the map.put(cleaned) fails since the key is coming from the cleaned element
(cleaned.owner).
Complete stacktraces, the first on entity loading and the later on collection loading:
Cause: java.lang.NullPointerException
