> in the previous DM 3 version, when you specify a service adapter without an autoconfig
field and with some callbacks (and with or without a callback instance object), then auto
config mode (on fields in the adapter class) is turned off.
> This is good, because mixing callbacks and auto-config mode (on class fields) may lead
to bugs difficult to diagnose.
> in dm4, there is a mistake: when you specify a service adapter without an autoconfig
field, but with callbacks on a callback instance, like this for example:
> {code}
> ServiceAdapterCallbackInstance callbackInstance =
>     new ServiceAdapterCallbackInstance(e);
> m.createAdapterService(OriginalService.class, null, null, /* no autoconfig field */,
 
>     callbackInstance, "set", "changed","unset", null, true)            
> {code}
> then the adapter class fields are auto-configured, even if no auto config class field
have been specified and if some callbacks have been specified.
> We should go back to the previous DM 3 behavior, which makes more sense: if some callbacks
are defined and there is no autoconfig field, then do not enable auto-config mode.
