Using the ZIP File System (`zipfs`) to update a JAR or ZIP file might corrupt that file. Corruption occurs only if the JAR or ZIP file contains a non-compressed entry. If the JAR or ZIP file contains only compressed entries, as is typical, then no data corruption occurs.

As a workaround, users can use the `jar` tool or the `java.util.zip` API to update JAR or ZIP files that contain non-compressed entries.
