I am using a proprietary intranet application, part of which is a Java applet. 
The applet has recently start throwing an exception at startup.  I cannot
provide the applet or provide a URL to the application, not without getting
fired, anyhow.

The last version of Seamonkey that this worked in is 2004-10-25-05 trunk
(Windows XP), so this is a very recent regression.

Here is the Java stack:

Java Plug-in 1.5.0
Using JRE version 1.5.0 Java HotSpot(TM) Client VM

So this works in 10/25 builds but is broken in 10/26 ones?

Well, now it is working fine again in today's trunk build.  I don't know what
happened - whether it was a real bug or just something weird about my
installation.  In any case, marking this WFM.
