--------------------------------------
The propblem here is that this given error is reproducing locally _VERY_ rarely, like 1 time in 3-4 days of active testing. On prod it's more often, but we can't use patched jar-s here...

[JBoss JIRA] (JGRP-2423) NPE during unlock operation
by Max Shaposhnyk (Jira)
[ https://issues.redhat.com/browse/JGRP-2423?page=com.atlassian.jira.plugin... ]
Max Shaposhnyk commented on JGRP-2423:
--------------------------------------
I have tried thal locally, adding output as follows:
{code:java}
public void addToPendingReleaseRequests(ClientLock cl) {
if(cl != null) {
String tmp=pending_release_reqs.stream().map(ClientLock::toString).collect(Collectors.joining(", "));
log.info(">>>>>>%s: Pending unlock requests: %s", local_addr, tmp);
log.info(">>>>>>%s: New Clientlock: %s",local_addr, cl.toString());
pending_release_reqs.add(cl);
}
}
{code}
And saw that none of the locks which are already in `pending_release_reqs` are null, neither new lock also not null and their adress fields also not nulls. So it seems quite strange for me. Probably some multithreading issue or something.

[JBoss JIRA] (JGRP-2423) NPE during unlock operation
by Bela Ban (Jira)
[ https://issues.redhat.com/browse/JGRP-2423?page=com.atlassian.jira.plugin... ]
Bela Ban commented on JGRP-2423:
--------------------------------
It would help to know which fields are null. If you can reproduce this, could you wrap the compareTo() call in a try-catch and print out the 2 owners, plus {{address}}... Perhaps this points to a different issue, because a field is expected to be non-null, but is null.
Meanwhile, I'm going to harden this by taking null fields into account...

[JBoss JIRA] (DROOLS-4891) Further Optimize Lambdas in Executable Model
by Luca Molteni (Jira)
Luca Molteni created DROOLS-4891:
------------------------------------
Summary: Further Optimize Lambdas in Executable Model
Key: DROOLS-4891
URL: https://issues.redhat.com/browse/DROOLS-4891
Project: Drools
Issue Type: Enhancement
Reporter: Luca Molteni
Assignee: Luca Molteni
Lambda shouldn't be externalized depending on the variable name but on the actual lambda.
So
person.name == a
person.name == b
Is effectively the same lambda and should externalized once.
Hint: we could rename the parameters to p1, p2, p3, promote the types to fully qualified names and get this result.

> Attachments: 1618-jgrp-patch.jar, NakReceiverWindow.java, screenshot-1.png

>
> We are using JGroups 2.8.1 and encountered a memory leak where it eventually ran out of CMS Old Gen memory. The heap dump revealed that the problem was in the xmit_stats ConcurrentHashMap of org.jgroups.protocols.pbcast.NAKACK.
> After much analysis here's what we found: when the system is under load, messages can start arriving out of order. When the receiver receives a higher sequence number than expected, it requests the sender retransmit the missing messages with the lower sequence numbers. The sender sends the missing message, however the bug in the NakReceiverWindow meant that the missing message was never purged from the Map that tracks missing messages (xmit_stats) because missingMessageReceived() was never invoked. Over time this Map grows and starts using up CMS Old Gen; the only way it would get reduced was when a server left the cluster and the missing messages were purged for that server.
> In JMX, the MissingMsgsReceived attribute of jgroups:cluster=*,protocol=NAKACK,type=protocol was always zero, confirming that it never purged any received "missing messages".
> When I looked at the most recent GA version 3.2.8 of NakReceiverWindow.java , it has the corrected logic that ensures that missingMessageReceived() is called. I checked the the most recent 2.x, which is 2.12.2, and found it also has the same bug in the logic as 2.8.1. This bug may apply to other 2.x but I did not check.
> Attached is the fixed NakReceiverWindow.java for 2.8.1.
> After applying the patch, the memory leak went away.
