Possible error in Java.g4

[lanyjie]

Another rule never used: "packageOrTypeName".

Well, that could should parse but i removed typeName. It cannot
distinguish a.b.c w/o type info so it just matches like this in expr:

|   expression '.' 'this'

I found that the rule "typeName" was never used anywhere in the grammar.
Therefore, it would be impossible to parse a statement like this:

java.lang.Object x = 1; //auto-boxing?

BTW, when antlr parse this, what's the depth of look ahead? because at
syntax level, it can't distinguish a qualified name from a chained
attribute access when "java.lang.Object" is parsed. So only when reached
'x' does it know what it is.
