Agree.

Personally, I really like error messages by javac. What do I care for  
column or character count: Those messages _show_ me the error  
position! (Kay mailed an excellent example)
So, if a parser error occurs, put k tokens from either side of the  
error site in a String, remember which character position in _this_  
String marks the defective character and put all that along with the  
line number in the created exception. For an end user, this is all I  
expect him to want.

Of course, if you want another program digest ANTLRs exceptions, that  
won't suffice.

Regards

Raphael
