Is it safe to install previous or older versions of Java?

Oracle highly discourages users from using older versions of Java. Installing old and supported versions of Java on your system presents a serious security risk. Upgrading to the latest version of Java ensures that Java applications will run with the most up-to-date security and performance improvements on your system. You can confirm that you have the latest version on the verification page. If installing an older version of Java is absolutely required, you must first uninstall the current version. See the instructions on the Mac uninstall Java FAQ.

Why will Applets not run after getting Java through Apple Software Update?

Apple disables the Java plug-in and Webstart applications when the Java update is done using Software Update. Also, if the Java plug-in detects that no applets have been run for an extended period of time it will again disable the Java plug-in.

Why is Java 7 available only for Mac OS X 10.7.3 and above?

The Java Runtime depends on the availability of an Application programming interface (API). Some of the API were added in Mac OS X 10.7.3. Apple has no plans to make those API available on older versions of the Mac OS.
