mindless:

Can you explain the issue in more detail? The stack trace looks like ssh-slaves failing to copy slave.jar, so I don't know why this is a "failure to detec JDK" issue?

Hmm - false alarm - all of a sudden it works now - even though I tried several times earlier today.
Maybe the box was just too slow (it's ancient) - or the fact that we patched the JDK fixed it.
Will reopen if this resurfaces.
Sorry bout the noise.
