Assuming no more than that JLS at some point read "Objective Knowledge", or at
least got past the first page, he will have seen Popper clearly claim, on page
one, that modern "epistemic logic" is mostly a misguided and misconceived
irrelevance when viewed in the light of the theory of knowledge defended in
that book.
There is no solution to Gettier Problems which rehabilitates 'JTB theory':
Gett-Probs are like the so-called 'paradoxes of induction' in that they only
create problems and paradoxes for those who cling to the idea "knowledge = JTB"
of the idea there is "induction" respectively (in fact, the so-called paradoxes
of induction prove to be equivalent to a demonstrable theorem in the calculus
of probability i.e. they are not unavoidable paradoxes at all but rather only
unavoidable if we cling to the idea of "induction"). Ditto for "Gett-Probs".

Just for the record, there is a new handbook of KEYWORD: epistemic logic.
Just mentioning it, to share the contents!
I wonder how much responds to Popper's programme, and how much to Grice's

Epistemic logic and, more generally, logics of knowledge and belief,
originated with philosophers such as Jaakko Hintikka and David Lewis in the
early 1960s. Since then, such logics have played a significant role not only in
philosophy, but also in computer science, artificial intelligence, and
economics. This handbook reports significant progress in a field that, while
more mature, continues to be very active. This book should make it easier for
new researchers to enter the field, and give experts a chance to
appreciate work in related areas. The book starts with a gentle introduction
to the
logics of knowledge and belief; it gives an overview of the area and the
material covered in the book. The following eleven chapters, each written by
a leading researcher (or researchers), cover the topics of only knowing,
awareness, knowledge and probability, knowledge and time, the dynamics of
knowledge and of belief, model checking, game theory, agency, knowledge and
ability, and security protocols. The chapters have been written so that they
can be read independently and in any order. Each chapter ends with a
section of notes that provides some historical background, including
references,
and a detailed bibliography.
Cheers,
Speranza
