MRJ 2.2.3 Oracle Certified, Caches Java Archives -- Apple has released Macintosh Runtime for Java 2.2.3, the latest version of its Java virtual machine. MRJ 2.2.3 includes bug fixes and performance improvements, reduces memory usage for Java applications that run for long periods of time, and offers better support for applets with double-byte file names. When using Internet Explorer 5, MRJ 2.2.3 is Gold Certified for use with Oracle Applications 11i, and Bronze Certified when used with Oracle Developer 6i, which makes the Macintosh slightly less irrelevant in an Oracle-driven enterprise environment. MRJ 2.2.3 also intelligently caches Java archives (JAR files) which contain segments of code used by Java applications. MRJ 2.2.3 will keep up to 100 MB of Java archives on your local hard disk; when you re-launch the Java applications, MRJ will ask if the JAR files have been updated and only download newer versions; this could save time re-starting Java programs. MRJ 2.2.3 still supports only Sun's JDK 1.1.8 specification rather than the now-standard Java 2. MRJ 2.2.3 is a 4.7 MB download, and is also available via Mac OS 9's Software Update control panel. MRJ 2.2.3 requires a PowerPC-based system with at least 40 MB of RAM running Mac OS 8.1 or better. [GD]
Turn Off Filename Extension Warning
In Leopard, Apple fixed an annoying aspect of working with the Finder in Tiger. Previously, if you changed a file's extension, the Finder prompted for confirmation. But since no one has ever accidentally changed a filename extension, Apple thankfully added an option to turn that warning off in the Leopard Finder's preferences. Choose Finder > Preferences, and in the Advanced screen, deselect Show Warning Before Changing an Extension.
