Hi Pavel,
I've changed it over to use a stateless session and I'm seeing the
same behavior. I've done some debugging and it seems to be very slow
loading up the SessionConfiguration due to all of the loading that
happens in ChainedProperties.
it could well be that.
When looking for property we search the available classpaths. With OSGi
you have to add a lot of classpaths to it, so it searches them all...
Other than telling it not to search the classpath for .properties files,
not sure what else we can do here...

Thanks,
Dave

Interesting. Normally it should be fast. Try to change your patter and
load binary compiled serialized package from disk. You can find it in
documentation.
Also consider using stateless session. Do you really need stateful
session?
