Just to add to this, while the `zip_util.c` changes are unique to our 8u patch, they are a conversion to C of the equivalent Java changes made in [JDK-8186464](https://bugs.openjdk.org/browse/JDK-8186464), with the intention to backport that change to 8u without the risk of [JDK-8145260](https://bugs.openjdk.org/browse/JDK-8145260), which introduces the Java-based implementation. So if there is a risk in this patch, it is likely a risk of a mistake in the translation to C rather than the general gist of the changes, which are present in the JDK's Java zip code. ------------- PR Comment: https://git.openjdk.org/jdk/pull/19678#issuecomment-2468614066
