;;; Commentary:

;; This code is taken from
;; https://github.com/hiredman/javap-mode/blob/master/javap-mode.el. This
;; package provides a mode for code disassembled by `javap', but also
;; installs a hook for disassembling the files. However, this is not
;; sufficient (for instance, it does not disassemble class files
;; inside jars).
;;
;; So this file is essentially the same as the original, but the
;; unconditional installation of `javap-mode''s hook is removed, since
;; `autodisass-java-bytecode' offers the same functionality (and some more).
