javax.net.ssl.SSLPeerUnverifiedException after installation of a new JDK on MacOSX

• After installing the new JDK (1.6.0_26) as normal user having the authentication dialog pop up for my admin account. I had loads of problems with javax.net.ssl.SSLPeerUnverifiedException popping up.
• I even was not able to start the /Applications/Utilities/Java\ Preferences.app/ and got a strange error.
• Logging in as admin did not help either, I still was not able to start the preference app.
• I downloaded the JDK as admin again and repeated the installation.
• I rebooted my system and now was able to open the preference app, reset to default options and the javax.net.ssl.SSLPeerUnverifiedException were gone.
