> On a server we still have Java7 installed, I'm getting these warning messages. They look like JUL logging but I'm not sure. I have the jul-to-slf4j bridge installed but these messages don't seem to be rerouted so I'm not sure what the source is at the moment.  I don't mind the warnings, as long as I can capture and properly log them.

>             script._warn << "jul->slf4j bridge install error [${e.message}]"
>         }
>     }
> {code} 
> I think my problem might be that those messages are coming up before I can hookup the bridge.
> Any insight on this you can give me?
> It would be nice if there was a way to suppress or delay these warnings. As it is , this is keeping me from using 2.5.0.
> In the meantime I am trying to get our admins to upgrade to at least Java8... but that might take some time.
