[rules-dev] getNestedConstraintPrefixLenght method in DRL6Parser.java

[Claudio Jesús Sánchez Casanueva]

I am studying the drools code and i have seen strange the method
'getNestedConstraintPrefixLenght()' in DRL6Parser.java: If i translate
that function to a regular expression in antlr lexer, it would be "ID? (
(DOT | HASH) ID)* DOT LEFT_PARENT", which have few sense. 

The header
of 'nestedConstraint()' describes the expected the expected result as "(
ID ( DOT | HASH ) )* ID DOT LEFT_PAREN constraints RIGHT_PAREN" : it
internally calls to 'getNestedConstraintPrefixLenght()', consumes the
numbers of items retuned by this, calls to 'constrains()' and cosumes a
RIGHT_TOKEN.
For me the expected results described in the header of
'nestedConstraint()' do not correspond with the real results.
