This problem may happen on the Mac depending on your history of Java installations and updates.

Basically, it is a problem doing SSL communication. In some Java 1.6 configurations on the Mac, the CA Certificates are simply... missing! Which is mind boggling to say the least. So the trick is to put back the certificates file somewhere where Java will find it.

Here is the procedure:
  • Download the "cacerts" file and check that it arrived in your "Downloads" folder.
  • Open the "Terminal" app (located in your Applications > Utilities sub-folder).
  • Type (or better, copy/paste) the following command and press Enter:

sudo rm /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/cacerts

(you will have to type your Mac administration password when asked)
This command removes the old redirection (which was going nowhere).

  • Then type or copy/paste this second command:

sudo cp -f ~/Downloads/cacerts /Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/lib/security/

This copies the file you downloaded to the right place.
