Subject Re: HTTP Session Clustering
Date Tue, 02 Apr 2019 10:02:18 GMT
Hi JB,

Wanted to provide a quick update. My ultimate environment is pretty complex with a lot of
bundles and XML-related components. To eliminate these dependencies I started with a plain
vanilla karaf, installed cellar, and built a very simple WAB.

The behavior is different, it looks better, but I have a different issue now. When the application
start and session clustering is initialized I get the following exception that persists and
keeps being thrown:

Let me know if you have any thoughts on what is happening.

I will investigate separately on what in my bundles might have been cuasing the original exception.

Thank you,
Oleg
