[9] Review Request for 8098835: [PIT] Endless loop in JEditorPane

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8098835
webrev: http://cr.openjdk.java.net/~ssadetsky/8098835/webrev.00/

It is regression of https://bugs.openjdk.java.net/browse/JDK-6866751.
Some important palaces in the BasicTextUI where width should be 
increased on the caret width have been missed.
