Any applet that uses the HTML <applet> tag does not load under Safari version 2.0.4 (419.3) on an Intel Macintosh. However, the same applet will load under (419.3) on Safari using a PPC Macintosh. You can verify this by using the current Apple release version of Safari (with Java 1.5.0_07) and the Java Duke test website. On an Intel Mac we see the gray coffee cup, but the applet does not load and the system console and Java console do not give any error messages.
I cannot reproduce this issue with shipping Safari/WebKit or ToT.
Examples such as <http://java.sun.com/applets/jdk/1.3/demo/applets/Animator/example1.html> work just fine for me.
Closing as INVALID.
