SPDE is thrown when the implementing OSGI spring service is destroyed, but you are still trying to call members on it.

For instance, a thread is holding a reference to a spring bean contained in a plugin , then in other thread  someone disables completely the plugin (thus destroying the proxy). Badaboum.
