Describe the bug

While looking in my metals log I found the following:

I'm running with

       -Dmetals.verbose=true
       -Dmetals.askToReconnect=false

No report was created, but since the error started with SEVERE I thought I'd post it.

Thanks for reporting! It looks like an empty path was sent to Metals, not sure why. The exception does show the full path, so it is probably just file:// Do you have any idea why something like this would happen? Anything specific about the workspace?

The exception seem correct since we were sent a wrong path and this might indicate a bigger problem.
