Attempting to view any applet from Internet Explorer using the Kernel JRE causes the browser to immediately crash.  This is evidently caused by interaction between the new plug-in and Kernel, as Firefox (which uses the old plug-in) works fine.  It fails even if all of the bundles have been downloaded;  the determining factor is whether or not the JRE has been completely reassembled.

EVALUATION There were two issues: 1) The new plug-in was looking for "client" and "server" JVMs, but not "kernel". 2) There was a race condition with the "initialized" variable in Java_VM.c. Presumably the fact that Kernel was having to perform a download, and thus dramatically altering the timing, was causing this to manifest.
