Yes I know. I was the one who did that about 6 years ago now :-)
They have to be disabled since OpenJDK doesn't have the sources.
I am pointing out that anyone changing how this is built would need
to be careful not to break that.

But jpeg might matter.
Oracle JDK does not/cannot use the system libjpeg for all purposes

ImageIO.
So a change would have to be confined to the OpenJDK and even if done
solely for splashscreen in Oracle JDK would mean two libjpegs being
loaded ..
The proprietary JPEG-extensions are already disabled in the Makefile,
when building OpenJDK (as opposite to Oracle JDK). From
openjdk/jdk/make/sun/jpeg/Makefile
...
# OpenJDK doesn't use the non-standard jpeg classes which we hope
to remove.
ifndef OPENJDK
FILES_m = mapfile-vers-closed
FILES_export += \

vpath %.c $(CLOSED_SRC)/share/native/$(PKGDIR)/image/jpeg
OTHER_INCLUDES += -I$(CLOSED_SRC)/share/native/$(PKGDIR)/image/jpeg

So, I don't think, this is still a concern (with OpenJDK, that is). Yours,
