make/mkdemo/Makefile contains legacy comments that are misleading:

# sound removed until 4401488 is fixed. - neal.gafter@eng 2000-01-03
# SUBDIRS = applets jfc sound
SUBDIRS = applets jfc jvmti management

# Solaris has one more demo...

# jni removed until 4401489 is fixed. - neal.gafter@eng 2000-01-03
ifeq ($(PLATFORM), solaris)
 SUBDIRS += jni
endif

1) sound has been removed from the JDK [note 1]
2) 4401489 is fixed, and this jni/Poller demo was always Solaris-only.

The comment lines should be deleted. Then we won't get confused and go off tracking down what happened (or didn't happen).
