Hi, Pankaj.
I guess that the problem is that the "image" is accessed w/o synchronization on 
"this"
like in other places, but it will be necessary to add one null check before usage of 
"image".
Also, it is not necessary to have a try/catch block in the test, just call the 
problematic method

Hi All,

Please review the following fix for jdk14.


Bug: https://bugs.openjdk.java.net/browse/JDK-8230235

Webrev: http://cr.openjdk.java.net/~pbansal/8230235/webrev00/

Issue:

Rendering HTML with empty img attribute and documentBaseKey set causes NPE

Fix:

The issues is introduced after https://bugs.openjdk.java.net/browse/JDK-8218674.

When the documentBaseKey is set, but img tag is not set, the image URL may not 
be complete and may not point to actual image. InĀ  ImageView class, when 
getWidth(ImageObserver) is called from the updateImageSize, it checks if image 
source is null and adds the ImageObserver (ImageView.ImageHandler) on the Image 
and sets the ImageView image as null. When getHeight is called, as image is set 
to null, it results in NPE.

We should verify that image is not null.

Testing:

I have tested it on Window, Linux and Mac.

Pankaj Bansal
