Yes - I see the problem has wider scope than I thought; I tried other
symlinks (created with mklink.exe from command prompt) and indeed I cannot
execute programs through these symlinks via explorer but can use them
successfully from command prompt.

I'm not a Java developer (C++) so I don't know what the scope of this
problem is (how many programs are affected given that there are other ways
to run java), but I found a link about this problem on an Oracle discussion
thread from April 1, 2015, so the problem has been around for at least three
months:

https://community.oracle.com/thread/3695801
<https://community.oracle.com/thread/3695801>  

As of now, I'm launching doxygen from Visual Studio in an nmake project and
I'm patching the path there (as above) - this will have to suffice until
Oracle fixes the problem or offers a safe alternative.
