Yes, it's using Eclipse's built-in editor support to do the 
highlighting. However, it doesn't use an ANTLR parser (in the usual 
sense) to do the outline generation but uses the ANTLR preprocessor's 
source wrapped with alternate versions of ANTLR's internal data 
structures that act as the glue between that preprocessor and the 
editor.

I'm not the original author of the plugin, but recently added several 
enhancements to the plugin. Unfortunately, due to the way it uses ANTLR 
internals, I have not been able to lift out the old ANTLR source and 
replace it with a more modern version, so some of the more recent 
constructs go unrecognized.
