>> Specification for CharBuffer::subSequence was missing clarification on the byte order of the returned CharBuffer. The returned order will always be the same as that of the original buffer. For example, subSequence() called on a CharBuffer with Little-Endian Byte Order will return a CharBuffer of Little-Endian Order. The specification has been changed to reflect this.

Testing for the Byte Order of different types of Buffer is generated via the template Order-X.java.template which serves to verify the original Byte Order of a Buffer and subsequently verify that the same Byte Order is present after operations such as CharBuffer::subSequence
