-------------------------------------
Summary: KARAF JsonInstaller throw error on Null dictionary
configuration
Key: KARAF-7255
URL: https://issues.apache.org/jira/browse/KARAF-7255
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.3.3
Environment: Karaf 4.3.3
Reporter: Róbert Csákány
The problem is we have own ConfigAdmin services which are initialized with null
Dictionary configuration object (in the OSGi spec the NULL value is allowed).
The problem the JsonInstaller always assumes that the
configuration.getProcessedProperties always returns with existing instance of
Dictionary.
{code:java}
Dictionary<String, Object> dictionary =
configuration.getProcessedProperties(null); File file = null;
if (dictionary.get(DirectoryWatcher.FILENAME) != null) {
file =
getCfgFileFromProperty(configuration.getProperties().get(DirectoryWatcher.FILENAME));
}
{code}
So there is a lot of exception in our case
