Patch: FYI: Re-merge CloneNotSupportedException

[Tom Tromey <tromey at redhat dot com>]

The libgcj-classpath comparison script pointed out a simple re-merge
waiting to happen.  I'm checking this in.

Usually for a re-merge I just put "Re-merged with Classpath" into the
ChangeLog.  Would it be better to try to dig up and use the Classpath
ChangeLog entry?

- * For example <code>CloneNotSupportedException</code> is thrown by
- * the <code>clone</code> method of <code>Object</code> to indicate 
- * that object does not implement the <code>Cloneable</code> interface.
+ * Thrown to indicate an object should not or could not be cloned. This
