Resolution: Fixed
Assignee: Richard S. Hall (was: Rob Walker)
I guess this is fine. I'm closing it as fixed.
> NPE in BundleRevisionImpl.close() when uninstalling a bundle
> ------------------------------------------------------------
>
> Key: FELIX-3160
> URL: https://issues.apache.org/jira/browse/FELIX-3160
> Project: Felix
> Issue Type: Bug
> Components: Framework
> Affects Versions: framework-4.0.0
> Reporter: Rob Walker
> Assignee: Richard S. Hall
> Priority: Minor
> Fix For: framework-4.2.0
>
> Attachments: Activator.java, Felix3160.zip

>
> There seems to be a case where m_content can be null when uninstalling a
> bundle, causing the following code to throw an NPE:
> synchronized void close()
> {
> try
> {
> resolve(null);
> }
> catch (Exception ex)
> {
> ((BundleImpl) m_bundle).getFramework().getLogger().log(
> Logger.LOG_ERROR, "Error releasing revision: " +
> ex.getMessage(), ex);
> }
>
> m_content.close();
> I've added a simple check for null around the close in my version to avoid
> the exception, which I'll check in.
> I'm not sure of the scenarios where this can legally be null at this point,
> and whether there's some nastier underlying circumstance that needs
> investigating. We see it under the following circumstances:
> * we register a listener that looks for framework STARTED
> * when triggered, this iterates all bundles and performs an uninstall on ones
> which we determine are zombies leftover from a previous run
> Aside from the fact we're calling uninstall from inside an event handling
> method, there doesn't anything else unusual about this code.
