Subject: Bug AMQ-810 not fixed properly yet?
MIME-Version: 1.0
Content-Type: text/plain; charset=ISO-8859-1

 Hello,

with a network of brokers and conduit subscriptions there is a known bug in=
 version 4.0.1, that under certain conditions prevents subscribers from get=
ting events.=20
(https://issues.apache.org/activemq/browse/AMQ-810)
According to the issue tracker the bug is fixed with version 4.0.2.
I know, that 4.0.2 is not released yet, so maybe I'm a little to early, but=
 I retested the problem yesterday with 4.0.2-RC4 (http://people.apache.org/=
~chirino/incubator-activemq-4.0.2-RC4/maven1/incubator-activemq/distributio=
ns/) and found the behaviour has changed, but it's still not correct. Now t=
here are duplicated events.
Should I submit a bug report, or is the bug-fixing for AMQ-810 still ongoin=
g?=20

Regards
Linda Floren

My test does the following:
I have two brokers A and B linked to each other with conduitSubscriptions=
=3Dtrue.
I have a publisher on A and subscribers with messageSelectors on B (and an =
identical set of subscribers on A for sanity check).

In 4.0.1 the behavior was as follows:
On broker B only the subscribers with a messageSelector that was a subset o=
f the messageSelector of the first subscription made on B received events. =
Subscribers with different messageSelectors received nothing.

With 4.0.2-RC4 the behaviour is as follows:
If on broker B n subscribers have identical messageSelectors, they receive =
each matching event n times!

Without messageSelectors everything works fine.
