Optimization: make threads return immediately if NAKACK has another active thread for the same sender
-----------------------------------------------------------------------------------------------------
Key: JGRP-457
URL: http://jira.jboss.com/jira/browse/JGRP-457
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assigned To: Bela Ban
Priority: Minor
Fix For: 2.5
In NAKACK, when a thread places a message for sender S into the NakReceiverWindow NRW, it subsequently acquires a lock on NRW (lock by sender) and removes as many messages as possible and passes them up.
If many threads do this at the same time, all threads but one are blocked, and - when finally unblocked - usually return. This causes context switches and possibly cache flushing, so a better way would be to have the threads check whether another thread is already removing messages using a CAS operation *before* acquiring the lock.
The effect should be that no threads will wait on the lock unnecessarily, and thus fewer context switches, and more threads available to the pool.

[JBoss JIRA] (WFLY-10796) Warning about JSF version 'NONE' is shown in logs
by Jan Kašík (JIRA)
[ https://issues.jboss.org/browse/WFLY-10796?page=com.atlassian.jira.plugin... ]
Jan Kašík updated WFLY-10796:
-----------------------------
Description:
Following warning is shown in log upon server start:
{code}
2018-08-02 16:13:28,487 WARN [org.jboss.as.jsf] (MSC service thread 1-3) WFLYJSF0005: Unknown JSF version 'NONE'. Default version 'main' will be used instead.
{code}
Seems like, that 'NONE' constant from WildFly code is somehow used instead of default 'main' value. Version 'NONE' is not specified anywhere, so this warning should not be present. From my point of view, it seems like I am trying set slot 'NONE' to be the default. But nothing like that is happening.

[JBoss JIRA] (DROOLS-4849) SudokuExample cannot solve hard samples any more in Drools 7
by Didier Loiseau (Jira)
Didier Loiseau created DROOLS-4849:
--------------------------------------
Summary: SudokuExample cannot solve hard samples any more in Drools 7
Key: DROOLS-4849
URL: https://issues.redhat.com/browse/DROOLS-4849
Project: Drools
Issue Type: Bug
Affects Versions: 7.30.0.Final
Reporter: Didier Loiseau
Assignee: Mario Fusco
It appears {{SudokuExample}} is capable to resolve the Simple and Medium samples, but none of the Hard ones. They resolve a few cells but end with
{quote}
Sorry - can't solve this grid.
{quote}
in the console.
With explain = true, I can see that the "single" and "hidden single" rules fire (not always both, depends on the puzzle), but clearly when it stops, at least the latter should still fire for some cells.
There is also a small bug in the code, which is that the {{unsolvable}} flag is not reset during setup, so when you get the above error you also get it for any other example you solve afterwards.
I have checked with Drools 6.5.0.Final (checked out the examples from GitHub) and the solver works fine. The Sudoku example appears to be mostly the same though.
I am running the examples with Java 8 from IntelliJ or command line, if that matters. I tested this on 2 different machines.
It is a bit unfortunate because it is the first example in the GUI.
Full console output for sample Hard 1:
