The new separate_jvm applet parameter (see 6627835) is very useful for isolating an applet into its own JVM instance. However, the JVM instances used to start up these applets still use the same timeout mechanism for tearing down the JVM instance once the applet has exited as is used for JVM instances that are allowed to launch more than one applet. We need to shut down the JVMs used to launch isolated applets more quickly.

This issue was raised on the Java Plug-In forum:
