java - Error - trustAnchors parameter must be non-empty -

I'm trying to configure my email on Jenkins / Hudson and I get a constant error

 java.security.InvalidAlgorithmParameterException: trust anchors parameter must be empty  

I have seen very good information online about the error, but I have not found any work. I'm using Sun's JDK on Fedora Linux (not Open JDK).

Here are some things I have to try. I tried to follow the advice to this, but I did not work in copying Cactus from windows and hosting my Fedora box Jenkins. I tried to follow it because I am trying to configure Gmail as my SMTP server, but it does not work either. I have tried manually downloading and transferring those cacert files and trying to move them to my Java folder using the variation of the commands on it.

I open for any suggestions because I am currently trapped. I've got it to work with Windows Hudson Server but I'm struggling with Linux.

This strange message means that you did not find trustworthy specified or because of permissions for example could not be opened.
