Any reason why this might happen? It's probably something to do with how I'm loading the library using "Javaloader.cfc" but who knows... I'm using 1.3.0

Have you ever succeeded running the library using JavaLoader? Otherwise please post a little snippet that introduces this error. There is obviously something wrong but I need to reproduce it somehow and I need to know more.

I have seen this error too. The reason it happened for me was that I was trying to import a less file that did not exist using

@import "something.less";

We are also getting this when an imported file has a syntax error. We're currently looking at putting together a test case and possibly a fix if we can work out what's going wrong.

Actually, that pull request didn't fix the case of a non-existent file - that needs an extra null check in the exception handling. I've updated the original request.

FYI, for anyone reaching this via Google, and has linux servers & Windows dev machines: Make sure your imports have the correct capitalization + always use "/" and never "\" in paths.
