Not sure I follow you:
"
When a class loaded by a bundle's class loader attempts to load a native
library, by calling System.loadLibrary, the findLibrary method of the
bundle’s class loader must be called to return the file path in which
the Framework has made the requested native library available. The
parameter to the findLibrary method is the name of the library in
operating system independent form, like http. The bundle class loader
can use the mapLibraryName method from the VM to map this name to an
operating system dependent name, like libhttp.so.
"
As we have a classloader per bundle, it's loaded at each bundle startup.

Dear all,
As OSGi core spec says - native libraries are loaded once and they are
linked with classloader. Due the fact that bundle classloader only find
the native library for system classloader which performs load the DLL/SO
file is always loaded only once and remains in memory untill JVM shutdown.
For details see OSGi 5 Core Spec section 3.10, especially paragraph 3.10.2.

From what I understand BundleActivator warns when un bundle is
started/stopped, which is not exactly the usecase I would like.
The .so lib must be loaded once. The best thing would be to obtain an
event stating the bundle is installed so I may load the lib.
For the moment I added a class with a static part. I load the lib when
that class is loaded by the classloader, which is not very good but
does the job. I also put the bundle as singleton for extra protection.

Hi JP,
you can control the loading in the BundleActivator.

Dear Karaf,
I have a bundle which loads .so libraries. I would like this code to
run once. What is the easiest way to do so?
Best regards,
