        Regression was isolated by measuring CI builds.

        Additional benchmarks afftected:
        1% J2dBench-bimg_imageio-G1 on Linux-x64
        2% J2dBench-vimg_images_opq-G1 on Windows-x64
        2% J2dBench-vimg_shapes_gradient-G1 on Windows-x64
        2% J2dBench-vimg_shapes_solid-G1 on Windows-x64
