If you copy data into the clipboard (using the clipboard API's),
select text in a text field and hit Ctrl-C the selected text is not copied
into the JVM's clipboard.

	Run the attached test program
	 * click over the drawn text ("this is a test")
	    (this places the text in the clipboard). To verify,
	    goto some other window and hit the paste key. You should
	    see "this is a test".
	 * type data in to the text field (above the drawn text)
	 * select some or all of the data in the text field
         * hit Ctrl-C
	 * now hit the paste key or Ctrl-V repeatedly
	 * instead of seeing what was selected before pasted over and over again,
	   I see "this is a test" pasted !! If I go over to another terminal 
	   window and hit paste, what was selected in the test program is
	   pasted properly.
	   It looks like the JVM's system clipboard is not updated properly.

java version "1.2.2"
Classic VM (build JDK-1.2.2-001, native threads, symcjit)

It is not possible to access files copied to the system clipboard via
java.awt.datatransfer. Everytime I 'copy' files in Windows Explorer (either
by CTRL + C or menu or toolbar) and then run the Java application below, the
returned Transferable object is null.

Is this a bug or is it 'planned functionality'? If the latter, then why have Sun
gone to so much trouble to implement platform independent drag'n'drop but not
copy/paste!?!?

  To reproduce the problem, do the following:
1. Start Windows Explorer in Windows NT 4.0
2. Select some files
3. Copy the files by presing CTRL + C or the toolbar copy button or selecting
copy from the menu
4. Run the Java application below
5. The application should print out "Contents of clipboard are equal to NULL"

That is, Java cannot access 'copied' files in the system clipboard via the
java.awt.datatransfer classes and interfaces.
