In terms of signatures then the methods look like a reasonable start. 
For the javadoc/spec then there are several issues that will need 
consideration and you might get some ideas from the javadoc that we have 
in the existing Files.copy methods - for example, it will need some 
wording about errors that happen after some (but not all) bytes/chars 
have been copied, some words to make it clear that the async close or 
either stream or thread interrupt during the copy is specified to the 
stream/readers/appendable involved and cannot be specified. It might 
also be useful to make it clear that IOE is thrown when called when the 
source or target is closed.
