[11] Review request for 8198605: Touch keyboard is shown for a non-focusable text component

[anton . litvinov]

Hello,

Could you please review the following fix for the bug.
Bug: https://bugs.openjdk.java.net/browse/JDK-8198605
Webrev: http://cr.openjdk.java.net/~alitvinov/8198605/jdk11/webrev.00

The fix extends a number of the required conditions in the method 
"sun.awt.windows.WToolkit.showOrHideTouchKeyboard(Component, AWTEvent)", 
which should be satisfied for showing of the touch keyboard, by checking 
if the component is focusable or not.

Thank you,
Anton
