This came up in the review of JDK-8009397, but after that fix had been pushed.

Hi Staffan,

Thank you for this discovery!
It looks good, but I have a couple of comments.

It seems, there is one more problem in this code:
  68 /* check for NULL path */
  69 if (p == pathname) {
  70 continue; <== Endless loop if we hit this line
  71 }

Do we need to do 'pathname++' before continuing at the line #70?
It is going to be endless loop in cases there is a PATH_SEPARATOR
at the beginning of paths or two PATH_SEPARATOR's in a row.
These would be incorrect path lists but the code above is targeting exactly such cases.
