Just to clarify that my insertion offset is zero, that is, attempting to
replace "ab" with "foo(a,b)".

Double-check with debugging sessions, still something is wrong. My
replacement offset is zero, that is, positioning at the 'a' in "ab",
which is to be replaced. My replacement length is 8, which is the
length of "foo(a,b)".
And keep encountering the below exception.

Dud! the replacement length to use is 2 NOT 8; it's the length of the
text to be replaced by the new text. I had done ContentAssist
before...Somehow misunderstood the parameter description!
