Java Kernel is currently spawning an instance of unpack200.exe for each downloaded bundle. CreateProcess is unfortunately too slow for this to be a viable solution, particularly under Windows Vista.

A slight change to ZipEntry allows us to use the Java version of unpack200 without initializing the time libraries. This resolves the performance problem without creating a core dependency on the very large lib/zi data.
