Apart from the added query, Change LGTM. test/jdk/java/awt/FontMetrics/ExtremeFontSizeTest.java line 39: > 37: /* > 38: * @test > 39: * @bug 8328896 8357672 I thought Freetype rasterizer is used on all platforms(Linux, Windows & macOS) by default. Since Freetype is part of JDK. When i run this test on macOS without any updates from this PR on baseline code, i see that all Fontmetrics in System.out() are non-zero and match before and after extreme parameters. Is this behaviour okay? I was expecting mismatch in FontMetrics on macOS also. If this test is supposed to catch issues on particular platforms. Do we need to make it specific to some platforms? ------------- Marked as reviewed by jdv (Reviewer).
