Hi Karaf users,
I have a Spring bundle which calls a third party library which itself calls a
native library. Because of some unfortunate yet understandable decisions of the
third party, I cannot have a @Bean created more than once.
What's happening for me is that the first load of Karaf and initialisation of
my bundles, everything works fine. But on the second load, I hit
UnsatisfiedLinkExceptions with the message that "already loaded in another
classloader".
It seems that somehow after the first successful run, my Spring configuration
is being loaded twice.
My bundles:

The spring application is #83 (enigmatically called "data") and has a Spring-DM
configuration file which just creates a JavaConfig bean, one of which is being
instantiated twice. I put some logging into this bean definition:
System.out.println("Making a database from: "+
Thread.currentThread().getContextClassLoader());
On the second load of Karaf, this line appears twice with "Making a database
from: BundleDelegatingClassLoader for [null (data)]" for both outputs, the
second of which throws the UnsatisfiedLinkException and fails to load the
bundle. If I stop and start the bundle again, the same thing happens. If I rm
-rf data and re-run Karaf the application works fine after installing the
necessary features.
Any suggestions?
Best, Dan.
