Issue: Ref: Webkit 619.1 javafx.web/src/main/native/Source/WebCore/platform/graphics/ImageSource.cpp refactoring in 620.1 In the case of the canvas pattern using a transform property filled with an SVGMatrix() created by an SVG element, `frame.m_nativeImage->size()` calls `NativeImage::size()` from NativeImageJava.cpp. In this scenario, `*m_platformImage->getImage().get()` may be invalid, as the image decoder has already populated `frame.m_size` during image metadata caching.
Solution: To avoid potential invalid accesses and unintended size resets, only update `m_size` if the frame does not already have a valid native image. ------------- Commit messages: - 8347937: Canvas pattern test fails and crashes on WebKit 620.1 Changes: https://git.openjdk.org/jfx/pull/1740/files Webrev: https://webrevs.openjdk.org/?repo=jfx&pr=1740&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8347937 Stats: 20 lines in 2 files changed: 18 ins; 2 del; 0 mod Patch: https://git.openjdk.org/jfx/pull/1740.diff Fetch: git fetch https://git.openjdk.org/jfx.git pull/1740/head:pull/1740 PR: https://git.openjdk.org/jfx/pull/1740
