The example Erik gave: make jdk-only JDK_FILTER=java/awt

Be aware that this workaround is of limited use, since it does not assist in
recompiling dependent packages, if the public api of java.awt was changed,
you need to know the 79 other packages that depend on java.awt and
recompile those
manually. sjavac does all this for you. Please try build-infra with
--enable-sjavac
