Patch: Fix for PR libgcj/1906

[Tom Tromey]

I'm checking this in.  This fixes PR libgcj/1906.  I believe it is
fairly low risk, so I think it is acceptable pre-branch.

2001-02-07  Tom Tromey  <tromey@redhat.com>

	Fix for PR libgcj/1906:
	* java/text/MessageFormat.java (setLocale): Use named class
	literals.
	(forName): Removed.
	(format(Object,StringBuffer,FieldPosition)): Special case if
	argument is an Object[].
