I'd doubt that.

A JVM will open the zip file, search for the class file they need to
open, read the bytes from the class file and then transform it into an
in-memory representation.  The .class format works well as an on-disk
format, but it sucks as a data structure for actually running Java
from.  Therefore every JVM loads all of rt.jar separately.

(however, JDK 1.5 appears to do some magic when it installs to pre-parse
some of the classes, but I've not dug into this much it is
arch-specific. These files are not zip files and may well be memory
dumps of the parsed classes, so can be loaded in a single step)
