Re: [equinox-dev] Meaning of a SCR warning message

[Stoyan Boshev <s.boshev@xxxxxxxxxxx>]

Hi Michael,

This message means there is a duplicate attempt for binding a service to 
a component instance.
Can you reproduce this every time you run your application or it just 
happened once?
Does your component have more than one references and at least two of 
them are satisfied by one service object (one service object 
implementing multiple interfaces)?
I reviewed the DS code and I think the most possible reason for this 
warning might be that your component has more than one references and 
their interfaces are implemented by one service object. This way SCR 
will attempt to bind one and the same ServiceReference object for one 
component instance more than once (depending on the count of component 
references covered by the ServiceReference's interfaces). I think this 
warning is not needed since this is a pretty standard situation. It 
should be removed or transformed into a debug message.
If the reason for the warning is the one I described above, you should 
not worry about it and you should ignore it.
