re: IntegrityChecker Java

UPDATE: 3.0 fc3 is now posted

...

Considerable effort has gone into this new release.

The key new feature is extended file attributes (xattrs) in addition to the icjh files, supported on macOS and Linux*. This new feature is completely seamless (nothing new to learn).

In particular, extended file attributes store hash info in addition to the icjh files.

This comprehensive and unrivalled solution means that all files can be covered, and that hash info travels seamlessly with files that are moved. Even into the Cloud (macOS, iCloud and similar).

* Windows has no support for extended file attributes; there is no apparent way to support the feature.
Linux works well with attributes, but is inferior to macOS in that it has limited intelligence on preserving attributes during file copy or similar.

Other improvements:

• Tested and working on Ubuntu and Debian Linux, Microsoft Windows, macOS.
• Use of file IDs via xattrs to locate missing files and folders definitively.
• Improved preferences and settings for more control over status reporting and errors reporting.
• New info and sync commands.
• Memory usage reduced by up to 10X.
• Improved summary output.
• Improved scanning speed (somewhat balanced-out by support for xattrs).
• Both Windows and Linux now open prefs files and help files automatically just as on macOS.
• Numerous improvement, code overhaul, bug fixes for various special situations.
• Support for the latest version of Java 18 (requires Java 16 or later).
