On my Win7 host, which has Java, there's not
HKEY_LOCAL_MACHINE/SOFTWARE/JavaSoft.

Below is my registry export for the "JavaSoft" key. I have both the 64-bit Java
JRE, and the 32-bit Java JRE, installed, here on my Windows 8.1 x64 machine.
There's some version info in "Java RunTime Environment", but also version info
in
"\Java Runtime Environment\1.7.0_51\MSI" Hope this somehow helps.

Eric,
Do you have a similar entry?
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit\1.7]
"JavaHome"="C:\\Program Files\\Java\\jdk1.7.0_51"
"MicroVersion"="0"

I'm not sure that windows would ensure it's in the path. cmd.exe doesn't find
it on my machine. There's probably a Registry key that contains the path to
the executable...
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\jarfile\shell\open\command does,
but I have no way of knowing whether it's universal.
FYI, we want "-version" not "--version". "--version" gives an error, I think.
A bigger issue is that nobody has yet written the java half of the BOINC API
(that I know of).

It should be the same. java.exe and/or javaw.exe should accept the --version
option.

Sure, we should add JVM detection to the client. Then we can use the plan class
mechanism to make sure the client has the required version of Java.
On Unix this seems to be easy: run java --version. On Windows I'm not sure how
to do it; does anyone know?

But I have been planning to add JVM detection to the core client on unix for
some time. It's one of those things I never get around to doing, though.
