Yeah, the problem is that Karaf itself isn't a container for Camel or CXF and we have some users that just want to plain JRE without any tweaks for running SAAJ because they don't care. ServiceMix on the other hand is dedicated to host such applications, so that's why the default config works better. I'm ok with the idea of profiles in karaf, but we need to make sure we don't end up with having to include and depend on all apache projects, as Karaf itself has imho no purpose of becoming a default distribution of CXF, Camel, ActiveMQ, Directory, etc... I think each project could easily provide a karaf features so that they would easily be deployed in a bare Karaf, but at some point, it does not really scale nor make sense to put everything back into Karaf.
Tweaking the system properties is sometimes needed depending on what you need to deploy, because OSGi is lacking on certain areas (or because the JVM isn't really modular, depending on how you see things). Some people are happy with using the JAXB implementation from the JVM without being able to change it easily, some people may want to be able to deploy those as OSGi bundles. Karaf can't do both at the same time. Another point, is that the amount of third party dependencies is becoming increasingly important in Karaf, and that's really becoming a problem for simply releasing Karaf in an efficient manner. So I'm tempted to say that we should push back on those projects and have them provide karaf features, rather than having karaf providing features for those. I'm mostly thinking here about pax-web and the war support (which is really cool, no doubt on that) and aries and support for things we don't embed by default (jpa, etc..). I certainly don't have a good answer yet, but I just want to make sure everyone is aware of the potential problem. If we keep adding dependencies, our release cycles will necessarily be longer and longer .... For example camel has a release cycle of one minor version every few months, ServiceMix even less, while CXF has much less external dependencies and manage to keep a high frequency of releases. 2.2 could have been shipped early december, but we were waiting for aries. Now aries has been released, but we still have some snapshots dependencies on some felix or ops4j components. And we've added stuff that's not completely stabilized. Once again, I'm just trying to state facts so that everybody understand the situation. I'm personnaly not really happy that the 2.2 release is planned since 2 months but still can't get out and I think it clearly means that we're going in a wrong direction somehow .... Sorry for the rant. There are a bunch of unrelated things here, ...
