JDK-8017777 is a well-known limitation of the Oracle JRE which will not be fixed. Basically it means that if a JVM opens a file using, and that file changes on disk while it is open, the JVM may crash. The application developer is simply responsible for ensuring this never happens. is a workaround to avoid the crash; it does not address the underlying application bug. In fact the crash per se only affects Unix machines: on Windows, you would be physically blocked from changing the ZIP file while it was open, or conversely from starting to read a ZIP file while something else was writing.
