What you are seeing is an example of cascaded exceptions--the first 
exception had the line number set, but after that was caught and a 
second exception thrown, the second exception did not have the line 
info set.  Run antlr under a Java debugger and set it to catch ANTLR 
exceptions, then look at the appropriate field in the Exception
