public abstract class PigRecognitionException
extends org.antlr.runtime.RecognitionException

Subclass of Antlr RecognitionException which should be the parent class of all parser related exception classes. We need this layer because of the line number problem in tree parser in Antlr-3.2. You will need a token where the exception occurs in order to instantiate an instance of this class.
