;; Use LSP for java mode. Mostly copied/inspired by github page:
;; https://github.com/emacs-lsp/lsp-java
;;
;;; Code:

(use-package lsp-mode
  :hook java-mode)

;; Seems I have to demand load this or it's not availble when
;; opening a java file.
;; 2018-07-18: switch to defer with timeout instead of demand
