I think that question is self-explained :-)
When I browse to Application eclipse send me an error.
rubdottocom almost got it. The problem is, that the path contains spaces. If you write a new shell script with the following content:
'/Applications/Google Chrome.app/Contents/MacOS/Google Chrome' $1
Eclipse can launch a new Chrome instance with it. Sadly, this way it is not possible to open a new tab in an already running instance, as the script exits with the following error message:
[21043:2307:292361872340725:ERROR:process_singleton_mac.cc(102)]
Unable to obtain profile lock.
