This morning after firing up the mac I noticed one of those grey "exec" icons sitting on my dock. Hovering over it, it comes up with the name "bin". It also said it wasn't responding so thought I'd force quite. I realised that it would bugger off then pop back up again.

'Show in finder' brings up a Java file in the system folder so I'm thinking it may have to do with the last java update I did last week.

Google doesn't know what I'm talking about so does anyone else have this and how can I get it to bugger off from my nicely organised dock? 

Thanks
