In a JSP mode file, if I type { at the end of a line, I correctly get the corresponding } immediately after it.
If I then hit Enter, the closing } is indented, but it’s indented one level too far out (to the left).
I’m on the Sublime 3 dev build, latest one I think. It’s a fairly recent regression. It seems to be limited to JSP as far as I can tell; Java and JavaScript files are fine, as is Clojure mode (though I’m less picky there).
