I wonder why build time information is different from Windows > and Linux. @tkiriyama I have created https://bugs.openjdk.org/browse/JDK-8288396 for the approach I championed above, i.e. to always build reproducible instead. As part of this, the `-Xinternalversion` time stamp should be of the same format for all platforms, given the same set of options to `configure`. The associated PR is https://github.com/openjdk/jdk/pull/9152. Can you verify if this solves your issues, and if so, close this bug? ------------- PR: https://git.openjdk.org/jdk/pull/9081
