Why is there no javax.smartcardio package in Java SE 7/8 API?

I have been looking for a while and I cannot find the Java package javax.smartcardio

in the official Java API. I've looked at these two different Java APIs:

http://docs.oracle.com/javase/8/docs/api/

http://docs.oracle.com/javase/7/docs/api/

I thought it javax.smartcardio

was the official Java package. Now I am wondering why this cannot be found in the official APIs?

The only way to find a package is with an Internet search engine. Google brought me to this page: http://docs.oracle.com/javase/7/docs/jre/api/security/smartcardio/spec/javax/smartcardio/package-summary.html
