It could, maybe something like "The length of the input byte (or character) sequence." would work?

This makes changes to the copyright headers of of the generated source files `UnsupportedCharsetException.java` and `IllegalCharsetNameException.java`. These can be found under a jdk build in `support/gensrc` and the headers update after running `make jdk-image`. Perhaps the build is out of date? These changes are harder to track as the source is not checked in.
