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

<pre>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?
