How can you tell if JAVA_HOME contains a JDK in a Windows batch file?

Is it possible to tell if a JAVA_HOME system environment variable contains a JDK within a Windows batch file?

If you're checking to see if the compiler exists, you could do something like:

if exist %JAVA_HOME%\bin\javac.exe (
   ...
) else (
   ...
)

You could look for %JAVA_HOME%\bin\javac.exe (or whatever it is, I assume exe). That should not exist in a JRE, only in the JDK.
