I'm calling compass from scripting container.
When trying to use 'compass watch' command.

The following error occurs:

NoMethodError on line ["87"] of path/to/gems/fssm-0.2.10/lib/fssm/path.rb: undefined method `is_virtual?' for <Pathname:/tmp/1384933325506-0>:Pathname

I checked the code of fssm. And found that Pathname is a class extending ruby's default Pathname class. And it has a method `is_virtual?'

https://github.com/ttilley/fssm/blob/master/lib/fssm/pathname.rb
https://github.com/ttilley/fssm/blob/master/lib/fssm/path.rb

However, this method is_virtual? is not recognized by jruby.

I also tried to call 'compass watch' from command line using jruby. The error is the same.

Since it runs successfully in MRI. I suppose this is a bug of jruby.

Please check it.

Hmm this actually works on master but not on 1.7 branch. I will see if I can quickly bisect this.

Fixes #1245. Undefined method exception when using compass watch in j…
…ruby 1.7.8. This is actually a regression from native Pathname addition. Some methods which should use class of caller was instead using Pathname. This is far from clear since some Pathname methods do seem to use Pathname and not subclass.

Thanks for the second reminder on this as compass was completely broken.
