In 0.1.16, ChannelAsInput.readFully(ByteBuffer) throws an IllegalArgumentException: Not enough bytes available (0) to read 128 bytes, when a similar call using a ByteArray instead of a ByteBuffer works fine.

e.g.:

fun test(sbc: SeekableByteChannel) {
	val LENGTH = 128
	sbc.position(sbc.size() - LENGTH)
	sbc.asInput().readFully(ByteBuffer.allocateDirect(LENGTH)) // throws exception
//	sbc.asInput().readFully(ByteArray(LENGTH), 0, LENGTH)      // substituting this line for the one above works without exception
}
