[jira] [Created] (ARIES-1701) A Possible NPE
Hao Zhong created ARIES-1701:
--------------------------------
Summary: A Possible NPE
Key: ARIES-1701
URL: https://issues.apache.org/jira/browse/ARIES-1701
Project: Aries
Issue Type: Bug
Components: Blueprint
Affects Versions: blueprint-core-1.7.0
Reporter: Hao Zhong
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
