Re: [p2-dev] java.lang.RuntimeException: Attempt to access stopped agent: org.eclipse.equinox.internal.p2.core.ProvisioningAgent@65fa65fa
|
Can you enter a bug for this? What's supposed to happen is that when the agent is stopped, it tells all registered services to stop. In the method SimpleProfileRegistry#stop it joins any existing preference save job. This should ensure there is no preference save job running after the agent has been stopped. Maybe in your case you never access the IProfileRegistry service so that service is never created in the agent? Or, there could be a timing problem I'm missing. In any case, please enter a bug and CC me and I can take a look.

The ProfilePreferences.save() method
schedules a job with the IProvisioningAgent instance that I created and
am stopping:

IProvisioningAgent) line: 40

How can I safely stop an IProvisioningAgent
instance when there is a scheduled job that will access it? Is
this a bug?
