Hi JB,

Thank you for replying!

Karaf: 4.2.4
JDK: 8u202

Standard distribution. I have a feature that has the required features in the doc listed as dependencies:


<feature>http</feature>
<feature>http-whiteboard</feature>

<feature>cellar</feature>

Thank you,
Oleg

Hi Oleg,

Is cellar feature installed correctly (providing the hazelcast instance) ?

What Karaf version are you using ? Is it a custom distro ?

Regards
JB

Greetings,

I wonder if anybody ran into a similar issue. I followed the setup
instructions
here: https://karaf.apache.org/manual/cellar/latest-4/#_enable_cluster_http_session_replication

Now that Karaf runs I am seeing this exception:

I would appreciate suggestions on how to fix this.

Thank you,
