I'd say this one is fixed, because of 
https://code.google.com/p/openhab/source/detail?r=6ada85efd2c7#

Although I do have one remark:

    protected Map<String, BindingConfig> bindingConfigs = new ConcurrentHashMap<String, BindingConfig>(new WeakHashMap<String, BindingConfig>());

The WeakHashMap is not necessary, because ConcurentHashMap is a container, 
instead of a wrapper like Collections.synchronizedMap.
