EVALUATION

Where the transfer methods use memory mapped I/O then closing the channel has no effect. Ths test already skips this sub-test on Solaris for this reason and should be skipped on Linux aswell. This bug will track updating the test to disable this sub-test. For jdk7 we need to re-examine this area ( minimally the transferTo method should throw AsynchronousCloseException and maybe it is possible to amaned the specification to allow for implementations where the closing the channel doesn't interrupt the transfer).
