I try to clean up the data folder, restart Karaf v2.3.3 and then install
cellar again, do the following steps:
1. Start Karaf, create a new cluster group called "test", and then shutdown
Karaf.
2. Restart Karaf again, find that cluster group "test" is shown in the
cluster group list.
3. and then create another cluster group called "test2", shutdown Karaf and
restart Karaf again
4. fire cluster:group-list to show the cluster group list.
5. find that cluster group "test2" is not inlcuded in the cluster group
list.
Sometimes, cluster:group-create may create and save the new cluster group.
Somtimes, it cannot save the newly cluster group.
The screen dump is as follows:

Subject: Re: Cellar don't save the newly created group settings
For the NPE, I already created a Jira about that (I saw that).
Regarding the cluster group, it works for me.
Did you clean up the data folder ?
When you did a cluster:group-list, you see the list of groups (before the
restart) ?
Let me check on Windows.
Regards
JB
