Hi folks,
After upgrading an existing karaf application to the latest karaf
version (4.2.2) I ran into startup issues.
To isolate the problem I revived an old example project and tried to get
that one working first. This example project WicketKaraf can be found on
github: https://github.com/misl/Samples . Please discard the other 2
projects in there, they still need to be upgraded. So only WicketKaraf
folder is applicable.
Unfortunately building this project yourself might not be
straightforward due to: PAXWICKET-489
<https://ops4j1.jira.com/projects/PAXWICKET/issues/PAXWICKET-489> and
PAXWICKET-490
<https://ops4j1.jira.com/projects/PAXWICKET/issues/PAXWICKET-490>. I
have yet to get some response for these issues.
Now the funny thing is, when starting all features manually
(feature:install) everything works just fin. But when trying to
automatically start my features on startup (bootFeature) it fails.
On first start:

Looked this one up, but I could not find any clear resolution to solve
this. I probably have to add something to the boot features section in
my assembly pom.
Don't know why but tried to start the application multiple times. The
strange thing is that that on a next start (bin/karaf) I got a different
error
On second start:

Guess what, now to starts without any problems.
To me this appears to be a timing or bundle start order issue.
Unfortunately I lack the Karaf experience to resolve this myself.
Any help in resolving this is highly appreciated.
Kind regards,
misl
