At least the native call swapchain->present dows not return that error code (https://learn.microsoft.com/en-us/windows/win32/api/d3d9/nf-d3d9-idirect3dswapchain9-present). I did not look decisively into all the native calls behind D3DRTTexture#readPixels.

We are currently using jre 11.0.19 with javaFX as a browser. Since it appears that the checks have passed, we will want to obtain the fix asap (although the Oracle bug report doesn't indicate a fix is ready). Please indicate when we can get the fix, and whether it be integrated into another version of the jre or whether it will be a separate javaFX download. Thx.
