	* java/nio/channels/FileChannelImpl.java
	(FileChannelImpl(String, int)): Removed.
	(FileChannelImpl(File, int)): Added. Check if opened file is a
	directory.
	* java/io/FileInputStream.java(FileInputStream): Fixed javadocs.
	Call FileChannelImpl(File, int).
	* java/io/FileOutputStream.java (FileInputStream): Call
	FileChannelImpl(File, int).
	* java/io/RandomAccessFile.java (RandomAccessFile):
	Call FileChannelImpl(File, int). Switched constructors around.
