[jira] [Created] (KARAF-1715) Occasional freeze on feature:install
webconsole
Ioannis Canellos created KARAF-1715:
---------------------------------------
Summary: Occasional freeze on feature:install webconsole
Key: KARAF-1715
URL: https://issues.apache.org/jira/browse/KARAF-1715
Project: Karaf
Issue Type: Bug
Components: karaf-webconsole
Affects Versions: 3.0.0.RC1, 3.0.0
Reporter: Ioannis Canellos
Priority: Critical
This is not something that happens all the time, so it might require a couple of attempts in order to reproduce it.
On a clean Karaf container feature:install webconsole can freeze and never return. When this happens CTRL-C does not stop the command execution and the only way to recover is a restart of the container.

Christian Schneider commented on KARAF-1715:
--------------------------------------------
I found a simple workaround. If you first install the http feature and then the webconsole it works. I think the issue might be that the webconsole servlet starts while the pax web config is installed which triggers an update of the ManagedService in pax web. This update restarts the servlet controler and there the block seems to happen.

----------------------------------------
It seems the problem is caused by pax-web being reconfigured while the webconsole is registering servlets.
Given pax-web does not unregister and re-register the http service, the console is not aware of the change.
