Thanks for clarification Tom. Now I understand that the stack trace is probably not related to the problem with re-configuration of modules on Karaf4.
But is the issue with re-configuration already known please ? I’ve tried to find some project using karaf4-parent and using Blueprint configuration of modules, but I haven’t found any. Is IoTDM project the first project testing it ?

When registering a service instance, it tries to create a proxy for it (for the quiesce functionality which isn't important) - on failure it uses the original instance (lucky for us). This happens sometimes - not sure why - it's an issue in the Aries Proxy lib. It would be nice if it used the JDK proxy APIs for interfaces as that's robust and only used the ASM stuff when proxying a concrete class as the JDK proxy API doesn't support that. OSGi services normally advertise an interface anyway (best practice).

I’ve done some draft changes of onem2m-core module and it’s submodules. Some of the submodules are using Blueprint configuration. I have a problem when I’m running Karaf4 distribution and I try to re-configure some of these modules through RESTCONF. First time everything works and module is re-configured successfully but second time (and for all next attempts as well) I just receive 200OK but the changed configuration is not used (the module is not re-loaded using the new configuration). I’ve noticed a stack trace in logs, it’s attached. It’s printed during the first re-configuration (nothing is printed during second and all next attempts to re-configure the module). Could you let me know please, if it is some known issue or whether it works well in general and the issue is related to my changes only ? The same steps works well for Karaf3 distribution of IoTDM.
