maven fails to build a valid Certificat path to access with SAP JVM

I'm working on a SAP Mobile Platform installation. This is running on a KVM Windows machine
hosted on a Fedora 23 box.

First problem was a network setting. The windows machine had a fixed DNS resolver host set from
our company network, but now I'm not in this network.
So this was he first part to enable name resolution for

Next stop was, that maven failed to build a certificate path using the SAP JVM.

After a little searching  I found the hint here:

Just copy the file .../jre/lib/security/cacerts to your JAVA installation from a newer Java version.

After doing this, maven could access the central repo with SAP JVM.
