The jar this class (LocaleServoceProviderTool) is in is: rt.jar
So, make sure that your rt.jar is on your classpath

Eg. In my case rt.jar is in the directory c:\program files\java\jre7\lib or also in c:\program files\java\jdk1.7.0_55\jre7\lib

Yes, it would be the reason, this class is no longer present in Java 8.

The sun.* packages are not part of the public Java API and therefore should not be relied upon for correct application functionality. You have come across the very reason for NOT using them. Refer to for details.
