I might be mistaken (no ANTLR source tree at hands) but aren't you  
supposed to do:
"setTabWidth(4);" before starting to parse? E.g.

Parser myParser = new Parser();
myParser.setTabWidth(4);
myParser.axiom();

I think you're setting it every time you encounter a tab, but only  
after actually consuming the tab. This way, the first tab will always  
be mistaken, subsequent ones will be read correctly.
