`lastSym` is never initialized. It's OK for the first time, but should this be
reset for the next use (if any), e.g. somewhere around line 595?

Any reason for re-shuffling the order of operators? I'd expect new ones are
appended to the existing ones, or appear in the order of their declarations
above?
(or is this automatically generated, as described in the comment?)

`if (isLiteral) {` might be more readable.

Could be
if (Token.STAR != c || !isAxis) {
incrementCount(c);
}

`c` is not used.
