With a current 9 build (as of June 23, 2015) start SwingSet2. With JAWS running activate the Text demo (6th button). Click on the JEditorPane HTML demo tab. JAWS takes a very long time to respond. Tab down into the text area. JAWS again is very slow to respond. There is no problem with the latest 8u build so this probably deteriorated sometime during the development of 9.
