java.nio.charset.Charset.contains(Charset cs) is specified as follows:

     This method computes an approximation of the containment relation: If it returns true then the given charset is known to be contained by this charset; if it returns false, however, then it is not necessarily the case that the given charset is not contained in this charset.

But then the @returns clause says:

    Returns:
        true if, and only if, the given charset is contained in this charset

This should be amended to


    Returns:
        true if the given charset is contained in this charset
