Hi, Dmitry.
I have only the one question: the size 0,0 can be returned if the custom cursors are not supported. I wonder should our CustomCursor have an initial size, of it should have zero size?

> Hello,
> Could you review a fix for jdk9, please?
> 	bug: https://bugs.openjdk.java.net/browse/JDK-8173853
> 	webrev: http://cr.openjdk.java.net/~dmarkov/8173853/webrev.00/
> Problem description:
> Sometimes XQueryBestCursor may return zero-dimension to the code inside XCustomCursor.getBestCursorSize(). As a result the subsequent invocation of CustomCursor constructor will fail with IllegalArgumentException during scaling of the image.
> Fix:
> It is necessary to avoid scaling if getBestCursorSize() returns zero-dimension.
> Thanks,
> Dmitry
