Works perfectly!!

JSlider and JSSliderUI replaced with Java8 originals, with just very
minor changes.
JSSliderUI block increment, not unit
"Button" prefix for disabled text
Float missing nonstatic isInfinite()

j2sClazz refines Clazz.getStackTrace(n < 0), where this also shows
arguments. (Via swingjs.JSUtil.getStackTrace(-3), for example)

Slow in Firefox, but very fast in Chrome.

jalview.org added to direct-database list

 incorrect KeyEvent id being dispatched by JTextUI
 incorrect use of innerHTML instead of value in JTextAreaUI

definition

after loading app, issue Clazz.getProfile()
