Sun Java Plugin will cache applets and required jars to speed-up applet downloading. Even if IE is running in offline mode, java Plugin still trys to connect to the orginal supplying server and will fail to execute applet if connection cannot be established.
MS JVM will execute applet correctly if it can be loaded from browser cache.

Reproduce:
MS JVM & IE:
- Enable MS JVM in IE 6
- Get online and visit: http://java.sun.com/applets/other/Hangman/index.html
- now switch to IE offline mode, exit IE and get machine offline
- Again visit http://java.sun.com/applets/other/Hangman/index.html
- Applet will execute in IE correctly without connecting to orginal site

Java plugin & IE:
- Enable Java Plugin in IE and enable network loggin for Java Plugin
- Get online and visit: http://java.sun.com/applets/other/Hangman/index.html
- now switch to IE offline mode, exit IE and get machine offline
- Again visit http://java.sun.com/applets/other/Hangman/index.html
- Plugin will try to connect with original site (throwing IOException) and applet will NOT execute
