Hi Guys,
First, Glad to see felix 4.0.0 released and provide OSGi 4.3 new features.
Thank you for your greate job.
But I meet a small problem, that the
org.osgi.framework.launch.FrameworkFactory.newFramework() need a Map<String,
String> for its parameter now. It means that I could not pass a Object to
configMap.
Unfortunately, I need put a SystemBundleActivator to the framework, So you
will see codes like below:
configMap.put(FelixConstants.SYSTEMBUNDLE_ACTIVATORS_PROP,
Collections.singletonList(activator));
which is not allow in OSGi 4.3. I digged the source of Felix.java, there is
also some config parameter using non-string type, E.G.
m_logger = (Logger) m_configMutableMap.get(FelixConstants.LOG_LOGGER_PROP);
So I guess, if I still want to use Felix non-standard config parameter, then
I cannot use FrameworkFactory any more.
You know, I never noticed this, but yes that is correct. I didn't
realize that this was changed to <String, String>...if I did, I would
have probably pushed for <String, Object> in R4.3.
Is there anyway that I could still using FrameworkFactory? Any suggestion
will be appreciated. Thank you very much.
Internally, the Felix framework does not completely use generics, so
just by chance, you can probably still do it. If you create a raw Map
and then cast it to Map<String, String> when you call newFramework(),
then it will still work.
However, this is a short-term solution. We'll likely need to create a
FelixFrameworkFactory that allows you to pass in a Map<String, Object>.
Sort of sucks, since it will be non-standard API, but the fact is, if
you are passing in Objects as config properties then you are already
using non-standard API.

I think it should be changed to
