[jfx24u-fix-request] Approval Request from Jay Bhaskar
Important follow-on fix for canvas pattern issue
24-03-2025
I attached "canvas.html" which was taken from the failing CanvasTest unit test. That test fails to render on WebKit 620.1 (although, unlike the unit test, it doesn't crash).

// but we missed backporting it to 6201.1.

The test revealed issue with JNI call, looks like platform image pointer is either invalid or the class doesn't implement `getSize` method since the JVM stopped at void `jniCheck::validate_call`
