Long hailed as the only OS vendor to provide Java built in, Apple stumbled yesterday in the eyes of Java developers with the release of Mac OS X 10.3.9, the latest update to the “Panther” version of the operating system.
The update causes Java to crash with a segmentation fault error whenever it is started. Visiting a website containing a Java applet in Safari 1.3, the new browser version that is a part of the update, will cause the browser to crash.
The solution to this problem is to first ensure that you have the Java 1.4.2 Update 2 installed on your system. If you’ve kept up-to-date with your software updates, you will. Next, you need to manually download and (re)install Security Update 2005-002 for Mac OS X.
These steps are detailed in a support article at apple.com.
