Apple has confirmed some Java and Safari problems with its recent Mac OS X 10.3.9 update.
The company explains that the software update increased the size of some internal libraries. This had the effect of, "causing a mismatch between the shared archive of the Java classes and the addresses used by the Java virtual machine".
Symptoms of this problem are that Java applications and Java-enabled websites when using Safari may "have issues". Safari and standalone Java applications may unexpectedly quit or not launch.
Apple advises users to reinstalling Security Update 2005-002 as this forces the shared archive to be recreated - fixing the problem, "even though the issue is not security related".
Apple also offers a series of steps to check for and repair the flaw.
