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().
