At the following Japanese document link,
there is a miss(wrong) translation.

http://docs.oracle.com/javase/jp/8/api/java/util/regex/Pattern.html#splitAsStream-java.lang.CharSequence

In this documents,there is a method as splitAsStream().

http://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html#splitAsStream-java.lang.CharSequence

The original explanation was wrote as follows.
**********************************************************************
If the input sequence is mutable, it must remain constant during the
execution of the terminal stream operation. Otherwise, the result of the
terminal stream operation is undefined.
**********************************************************************

In the above document, input sequence is "mutable" is wrote.
By Japanese, the "mutable" should be translated as "KAHEN" not "FUHEN".

However in the above Japanese document,
[NYUURYOKU SEQUENCE GA "FUHEN" DE ARU BAAI] was wrote.
It is the incorrect translation.

Please modify the "FUHEN" word to "KAHEN" word by Japanese?
