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 += \
             sun/awt/image/codec/JPEGImageDecoderImpl.java \
             sun/awt/image/codec/JPEGImageEncoderImpl.java
    vpath %.c   $(CLOSED_SRC)/share/native/$(PKGDIR)/image/jpeg
    OTHER_INCLUDES += -I$(CLOSED_SRC)/share/native/$(PKGDIR)/image/jpeg
    endif
    ...

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