case WINDOWS:
/*
Windows silent installation is full of bad know-how.
On Windows, command line argument to a process at the OS level is a single string,
not a string array like POSIX. When we pass arguments as string array, JRE eventually
turn it into a single string with adding quotes to "the right place". Unfortunately,
with the strange argument layout of InstallShield (like /v/qn" INSTALLDIR=foobar"),
it appears that the escaping done by JRE gets in the way, and prevents the installation.
Presumably because of this, my attempt to use /q/vn" INSTALLDIR=foo" didn't work with JDK5.
I tried to locate exactly how InstallShield parses the arguments (and why it uses
awkward option like /qn, but couldn't find any. Instead, experiments revealed that
"/q/vn ARG ARG ARG" works just as well. This is presumably due to the Visual C++ runtime library
(which does single string -> string array conversion to invoke the main method in most Win32 process),
and this consistently worked on JDK5 and JDK4.
