Charles Moulliard commented on CAMEL-1966:
------------------------------------------

Just to inform you that this error appears also when Camel 2.1-SNAPSHOT is used within Apache Karaf Felix. I have this error since around 3-4 days (when switching from Camel 2.0 to camel 2.1-SNAPSHOT. That was not the case before. I must stop/start my camel bundle to be able to work with it.

1) At the karaf launch, the following error is generated :

{code}
karaf@root:/> Exception in thread "SpringOsgiExtenderThread-8" java.lang.IllegalStateException: BeanFactory not initialized or already closed - call '
refresh' before accessing beans via the ApplicationContext

        at java.lang.Thread.run(Thread.java:595)
{code}

2) My camel context is not started
3) To start it, I must stop my camel bundle. During the stop, here is the error generated :

{code}

{code}

I see also sometimes this warning in the log

{code}
