The "file" in question may well be something only the Java program knows about
- from the OS's point of view it might still be a non-existent or zero-length
file at the time the JVM exits.
It might also be that the JVM is better about telling the OS of its crashes
than it used to be?
Even if so, there are still no guarantees about the completeness or
consistency or usability of an OS file after a Java program leaves without
properly close()ing its connection to it. That much hasn't changed.
