Good catch. No, it isn't: I was experimenting with the various java* executables to see if there was a difference, and pasted the wrong interaction. The problem occurs for both files (and indeed many others!)<div><br> </div><div>I guess it could have to do with soft links. I tried copying the exe from the java folder itself into System32, but that had no effect. Even if the problem is soft-links though, I would expect directory-list to show the links! </div> <div><br></div><div>One thing I haven't tried is other folders. I'll give that a shot when I get home today.
