[JBoss JIRA] (DROOLS-5119) [Guided Rule Editor] Workbench BigDecimal value turns into 0.0 in DRL
by Bhala Hadkar (Jira)
[ https://issues.redhat.com/browse/DROOLS-5119?page=com.atlassian.jira.plug... ]
Bhala Hadkar commented on DROOLS-5119:
--------------------------------------
Thanks Michael. I'll test 7.34.0.Final on my side and let you know how it behaves.
> [Guided Rule Editor] Workbench BigDecimal value turns into 0.0 in DRL
> ---------------------------------------------------------------------
>
> Key: DROOLS-5119
> URL: https://issues.redhat.com/browse/DROOLS-5119
> Project: Drools
> Issue Type: Bug
> Components: Examples (Workbench), Guided Rule Editor
> Affects Versions: 7.34.0.Final
> Reporter: Bhala Hadkar
> Assignee: Michael Anstis
> Priority: Major
> Labels: drools-tools
> Attachments: DROOLS-5119-rule.png, Workbench-Guided-Rule.png, drools.png
>
>
> When I set up a Guided rule on Workbench having a comparison condition on one of the domain field of type Big Decimal then the int value entered through literal text disappears and turns into 0.0B.
> For e.g. if you look at this Guided Rule screenshot the literal value 100 turned into 0.0.
> !Workbench-Guided-Rule.png|thumbnail!
> Also in the drools the value becomes 0.0B.

[JBoss JIRA] (JGRP-2435) ClientGmsImpl ignores newer view during join
by Bela Ban (Jira)
[ https://issues.redhat.com/browse/JGRP-2435?page=com.atlassian.jira.plugin... ]
Bela Ban commented on JGRP-2435:
--------------------------------
OK, I was able to reproduce this, too.
I think the simple fix would be to change {{ClientGmsImpl}} -> {{ParticipantGmsImpl}} (or {{CoordGmsImpl}}) in {{GMS.installView()}}, which is synchronized.
> ClientGmsImpl ignores newer view during join
> --------------------------------------------
>
> Key: JGRP-2435
> URL: https://issues.redhat.com/browse/JGRP-2435
> Project: JGroups
> Issue Type: Bug
> Affects Versions: 4.1.9
> Reporter: Dan Berindei
> Assignee: Bela Ban
> Priority: Major
> Fix For: 5.0, 4.2.1
>
>
> We have random failures in a test that starts 4 nodes in parallel ({{org.infinispan.InitialClusterSizeTest.testInitialClusterSize}}). I get at least one failure if I add {{@Test(invocationCount=100)}}, but I did not get any failure when I did the same with {{org.jgroups.tests.ConcurrentStartupTest.testConcurrentJoinWithLOCAL_PING()}}, maybe because the Infinispan test sends some additional messages and sometimes changes how messages are processed.
> The problem seems to be that after receiving a {{JOIN_RSP}} and installing the first view, the GMS implementation is still {{ClientGmsImpl}} when receiving the second view, and the view is ignored. Because this second view already has all 4 members, there is no other {{VIEW}} message and the test just times out.
> I added some logs in TP and GMS for debugging, and this is what I see:

> To help debugging, {{TP.passBatchUp}} should really log the headers of the messages in the batch, and {{GMS}} and the {{GmsImpl}} subclasses should log at least a DEBUG message every time they ignore a view (even when {{log_view_warnings==false}}). I also suggest removing the default implementations from {{GmsImpl}} and updating the {{ClientGmsImpl}} javadoc, because it talks about handling {{ViewChange}} instead of {{JoinResponse}}.
