Apple has released a Java Update for Mac OS X v10.3.9 after a security patch caused certain websites not to work and the Safari Web browser to crash.
"After updating to Mac OS X 10.3.9, some systems may have issues with Java applications and Java-enabled websites when using Safari. Safari may unexpectedly quit, and stand-alone Java applications may unexpectedly quit or not launch. This update resolves that issue," Apple explained.
The patch for the patch is available for download through the Software Update system preference pane and has been posted to Apple's website.
You can check if you're affected by going to the Utilities folder inside the Mac Applications folder, opening the Terminal application, and typing "java -version", then pressing Return. If you receive a "Segmentation fault" message, the computer needs this fix.
