Fwd: Fwd: java -version different on Win vs Cygwin

[Pete Brunet]

Should the 64 bit Win installer also install the 32 bit program?  If not
it would be good to put a warning on download page.

I think I found the answer here:

Quote:
This is because Cygwin bash and Console are 32-bit applications, and I'm
running 64-bit Windows. With filesystem virtualization on Windows, when
a 32-bit process attempts to access %SYSTEMROOT%\System32, it is
redirected to %SYSTEMROOT%\SYSWOW64. Ironically named, System32 contains
64-bit applications, while SYSWOW64 contains 32-bit applications.

These give the same version:
Win 7 DOS prompt: \Windows\SysWOW64\java -version
Cygwin prompt: /cygdrive/c/Windows/System32/java -version

I get different versions when I do the following.  Why?

Win 7 DOS prompt: \Windows\System32\java -version
Cygwin prompt: /cygdrive/c/Windows/System32/java -version

Is that java.exe a stub that routes to a different java.exe?  How do I
control which java is activated?
