> Using Brooklyn 0.10.0-SNAPSHOT, running in karaf...
> A customer deployed an app, which uses entity and policy classes defined in
> an OSGi bundle (supplied via brooklyn.libraries). A simplified version of the
> catalog item is something like that below (where
> {{com.example.apps.MyTopLevelApp}} and {{com.example.policies.MyPolicy}} are
> Java classes in my-bundle.jar):
> {noformat}
> brooklyn.catalog:
> brooklyn.libraries:
> - file:///path/to/my-bundle.jar
> id: com.example.MyApp
> itemType: template
> version: 1.3
> description: My App
> displayName: My App
> item:
> services:
> - type: com.example.apps.MyTopLevelApp
> brooklyn.config:
> childSpec:
> $brooklyn:entitySpec:
> type:
> org.apache.brooklyn.entity.software.base.VanillaSoftwareProcess
> name: Sshable
> brooklyn.config:
> checkRunning.command: echo true
> customize.command: echo true
> launch.command: echo true
> brooklyn.policies:
> - type: com.example.policies.MyPolicy
> {noformat}
> This deploys fine. However, when one stops and restarts Brooklyn (so
> rebinding to persisted state) it gives the exception below:
