Aled Sage created BROOKLYN-409:
----------------------------------
Summary: Rebind fails in karaf, with app referencing classes in
catalog item's bundle
Key: BROOKLYN-409
URL: https://issues.apache.org/jira/browse/BROOKLYN-409
Project: Brooklyn
Issue Type: Bug
Reporter: Aled Sage
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:

Brooklyn does start up, but the policy no longer exists on the entity.
