<Swing Dev> [9] Review request for 8156185: JDK-8024858 (long tooltip delay) is not fixed but is easily fixed

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:

bug: https://bugs.openjdk.java.net/browse/JDK-8156185

webrev: http://cr.openjdk.java.net/~ssadetsky/8156185/webrev.00/

Scan through the GraphicsDevice#getConfigurations() may take significant 
time on some hardware configurations. But actually it is not needed to 
find the device configuration for the tooltip, because only the 
information about device bounds/insets is used then. So, the scan is 
replaced with device.getDefaultConfiguration().
