I couldn't verify Java 8 update 25 with Safari 8 browser

OS X version is Yosemite 10.10.1 (14B25)

I installed JRE 8u25.

I couldn't verify Java in the Safari 8.

At fist time of try to verify with java.com Applet, Safari asked to me to allow java.com. I allowed.

After waiting a long time, I receive a message that "We are unable to verify if Java is currently installed and enabled in your browser."

Restarting Sarafi or system has no echo.

In the Java Control Panel

• Java in the browser enabled.
• Exception Site List is empty.
• Certificates Lists all are empty.

In the Prerefences of Safari

• JavaScript is enabled.
• Internet plugins are enabled.
• Some web sites (java.com, www.java.com, etc) have allowed.
