Hello,
Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8159432
webrev: http://cr.openjdk.java.net/~ssadetsky/8159432/webrev.00/
The issue is connected to the restoring focus to the previously focused
window when there are a lot of focus restore requests are coming very
often (for example series of windows showing and hiding quickly). In
this case waiting for asynchronous focus causes nested waiting loop, and
if number of such requests is big enough the StackOverflowError is thrown.
To avoid this the 8139218 solution is revisited to manage the focus
restore synchronously only if it is possible and send a single
asynchronous focus request otherwise.
