---------------------------------------
Hello Amichai
I have done several iterations of your scenario without success (I mean without
{{NoClassDefFoundError}} :)). Tell me:
* what are your dependencies ({{Import-Package}} or {{Require-Bundle}})?
* does your {{common}} or {{bus}} bundle import ({{Import-Package}})
{{javax.net.ssl}} package?
* what is your ActiveMQ connection URL (I've tested
{{failover:(vm://localhost)}}).
* (_optional_) how did you manage to install {{activemq-broker}} feature
without patching
{{KARAF/system/org/ops4j/pax/url/pax-url-mvn/1.3.6/pax-url-mvn-1.3.6.jar}}
(see: https://ops4j1.jira.com/browse/BASE-48)

> Key: AMQ-4850
> URL: https://issues.apache.org/jira/browse/AMQ-4850
> Project: ActiveMQ
> Issue Type: Bug
> Components: OSGi/Karaf
> Affects Versions: 5.9.0
> Environment: Oracle JDK 7u45, Karaf 2.3.3 with activemq-broker
> installed from 5.9.0 feature
> Reporter: Amichai Rothman
> Assignee: Jean-Baptiste Onofré
>
> I couldn't find a way to recreate this consistently, but after repeating
> several times the following steps reproduce it:
> 1. Install custom Karaf 2.3.3 from scratch. Customizations include installing
> the activemq-broker feature using the featuresBoot configuration (along with
> a couple other unrelated features), and a dozen or so of my application's
> bundles in the deploy folder.
> 2. Start Karaf - everything works fine.
> 3. Shut down Karaf.
> 4. Touch my application's 'common' bundle (in deploy folder). The other
> application bundles depend on this one. This is *not* the bundle that uses
> ActiveMQ.
> 5. Start Karaf - it first starts all the app bundles (the old version I
> think), then it picks up the modified bundle timestamp and restarts the app
> bundles in what appears to be arbitrary order. This usually works, but once
> in a while the app's 'bus' bundle (which connects to ActiveMQ) fails to start
> with this exception showing up in the logs.
> 6. Interestingly, restarting the app or activemq bundles, or even restarting
> Karaf itself, doesn't fix things - once it enters this invalid state, it
> seems to stay stuck in it and continues with the same exception and with the
> app unable to connect to ActiveMQ. However, if I shut down Karaf and once
> again touch my app's 'common' bundle in the deploy folder and then start up
> Karaf again, it restarts the app bundles and this time everything goes back
> to normal, with a successful connection to ActiveMQ. So it looks like while
> the first occurrence is not recreated consistently, this state is not just a
> runtime thing but remains persisted somehow for as long as the app bundle
> files aren't modified.
