---------------------------------------
Summary: Incorrect usage of ServiceTracker.size() in UPnP Plugin
Key: FELIX-4013
URL: https://issues.apache.org/jira/browse/FELIX-4013
Project: Felix
Issue Type: Bug
Components: Web Console
Affects Versions: webconsole-upnp-plugin-1.0.2
Reporter: Valentin Valchev
Assignee: Valentin Valchev
Fix For: webconsole-upnp-plugin-1.0.4
There seems to be a small problem with the tracking code especially with the
following line (Activator.java):
if (tracker.size() <= 1 && plugin != null)
...
ServiceTrackerCustomizer.removedService() is supposed to be called AFTER the
service is no longer tracked. So in that method the size must be already
decremented. The code above will unregister the plugin if only one UPnP device
left in the system and it wouldn't be accessible through the web console.
The correct code is:
if (tracker.size() == 0 && plugin != null)
