wro4j chokes on less import inline statements

What steps will reproduce the problem?
1. create a less file that imports a css file inline
    @import (inline) "yourfile.css";
2.run wro4j

This causes a complete failure.

[INFO] processing group: yourfile.css
[ERROR] exitStatus: 1
[WARNING] Exception while applying NodeLessCssProcessor processor on the 
/yourfile.less resource, no processing applied...
ro.isdc.wro.WroRuntimeException: Error in LESS:
ParseError: Unrecognised input in /yourfile.less on line 2910, column 2:

2911  "yourfile2.css";

    at ro.isdc.wro.extensions.processor.css.NodeLessCssProcessor.process(NodeLessCssProcessor.java:116) 

I tried versions 1.7.0 and 1.7.7. on OSX.

Please provide any additional information below.

Running the command directly in node with lessc version 1.5 works just fine. I 
think it works in 1.4 aswell.
