State of applet isolation in JDK 1.4 and 5?

What is the state of applet isolation in JDK 1.4 and 5? Put another
way, if a QA department was responsible for testing two web pages with
applets that are essentially unrelated, but will likely be running at
the same time, what guarantees or assurances do they have with respect
to isolation of those two applets?

Is there good documentation that describes the sandbox that applets run
in, with respect to their relative isolation?

When I googled for this, I found a somewhat contrived (opinion,
perhaps) example using an undocumented static variable loaded by the
bootclasspath, which demonstrates one applet blocking an unrelated
applet. This reference was almost 3 years old, so I don't know if it's
still a problem in the latest JDK 1.4 release, or in Java 5.
