> Note: test/jdk/sun/java2d/OpenGL/ScaleParamsOOB.java fails on linux-x64 and linux-aarch64 (using libmesa software rendering) with a color mismatch error (expected=ffff0000 actual=ff000000 at x=40 y=40), similar to [JDK-8369335](https://bugs.openjdk.org/browse/JDK-8369335). The similar error on Windows (not observed during my testing) will be fixed for in a separate backport PR (https://github.com/openjdk/jdk25u-dev/pull/265), but not the issue mentioned. Created [JDK-8377908](https://bugs.openjdk.org/browse/JDK-8377908) to capture the issue.
