Description

I found that the CmUtils.getProperties method has a buggy code as follow:
try {
ConfigurationAdmin ca = bc.getService(caRef);
Configuration config = getConfiguration(ca, persistentId);
if (config != null)

{ Dictionary<String, Object> props = new CaseInsensitiveDictionary(config.getProperties()); BundleContext caBc = caRef.getBundle().getBundleContext(); callPlugins(caBc, props, service, persistentId, null); return props; }

else

{ return null; }

} finally

{ bc.ungetService(caRef); }

Here, before calling ungetService, the call chain BundleContext caBc = caRef.getBundle().getBundleContext() can throw NPE.

Indeed, a similar bug is fixed in ARIES-788. Please check this bug at https://issues.apache.org/jira/browse/ARIES-788?jql=project%20%3D%20ARIES
