(let [^JEditorPane html-table (editor-pane ...)] ...) should fix it. Or just set the caret position in the create function:
(editor-pane :caret-position 0) or use config: (config! editor-pane :caret-position 0) Dave On Fri, Feb 27, 2015 at 4:07 AM, Cecil Westerhof <cldwester...@gmail.com> wrote: > 2015-02-27 11:34 GMT+01:00 Gary Verhaegen <gary.verhae...@gmail.com>: > >> It means the Clojure compiler cannot emit the efficient bytecode >> directly, so it emits bytecode that calls the method reflexively. >> >> This only impacts performance, so if that code is not used much, it is >> not a problem. >> > > It is not used much, so it should not be a real problem. > > > > >> The underlying problem is that jvm bytecode is typed, so ideally the >> bytecode should be able to say "call method M of type T on object O".
