[antlr-interest] Bug in 2.7.6 with lexer option defaultErrorHandler = true

[Alexey Demakov]

When lexer option defaultErrorHandler is set to true,
antlr-2.7.6 generates error handlers with call of 

public void recover( RecognitionException ex, BitSet tokenSet )

but this method is defined only in Parser, not in CharScanner,
so it causes compilation errors.

antlr-2.7.2 "inlines" this method as

consume();
consumeUntil( tokenSet );

Workaround - define this method in lexer:

public void recover( RecognitionException ex, BitSet tokenSet ) throws CharStreamException 
{
  consume();
  consumeUntil( tokenSet );
}

Regards,
Alexey
