Hello,
Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8075084
webrev: http://cr.openjdk.java.net/~ssadetsky/8075084/webrev.00/
When a modal dialog is shown in scroll bar button click listener it
blocks all events targeted to the scroll bar owner window.
At the same time clicking on scroll bar button triggers a timer which
should adjust scroll bar value automatically until mouse button is
released, i.e. until mouse release event comes to the pushed scroll
button. So, this timer is not stopped by the mouse release event because
it is rejected by the modal filter. When modal dialog is closed the
timer continues to produce scroll adjustment events and the dialog is
shown again. Also the scroll button remains pushed and hovered all the
time (because it didn't get mouse release event).
In the suggested fix the timer is started only if the scroll bar owner
window keeps input focus after the adjustment callback and the scroll
button is reset otherwise.
