	java/nio/ShortBuffer.java,
	java/nio/ShortBufferImpl.java,
	java/nio/ShortViewBufferImpl.java:
        Fixed javadocs all over. Improved input error
        checking.

	* java/nio/Buffer.java
	(checkForUnderflow, checkForOverflow, checkIndex,
	checkIfReadOnly, checkArraySize): New helper methods
        for error checking.

	* java/nio/ByteBufferHelper.java
	(checkRemainingForRead, checkRemainingForWrite,
	checkAvailableForRead, checkAvailableForWrite): Removed
        no longer needed methods.
