Comments
This is a long-standing and well-known issue. Any time there is an Texture with a width or hight > the maximum texture width we will run into this bug. For rendering from images (Image / ImageView) we have implemented tiling, but that hasn't been done for rendering into an RTT such as with Snapshot, Canvas, or SubScene. See JDK-8088198.

This was misfiled; it is a graphics issue and not a scenegraph issue.

When checked in Windows 10, issue is reproducible in JDK 8, 9, & 10 8u144 : Fail 9-ea+181 : Fail 10-ea+23 : Fail There is no issue when only 'Scene' is created and height of Scene is 8193. But when height of 'SubScene' is made 8193, got NPE.
