[Joel Borggrén-Franck]

Can’t really comment on the makefile changes but I think this workaround is good for now. Thumbs up

cheers

With this change, Sjavac will start acting correctly again and not miss any files that need to be recompiled. The approximation is course however, we should still fix https://bugs.openjdk.java.net/browse/JDK-8054717 to properly only recompile what is really necessary. Still, this workaround does add value compared to running without sjavac. With this change and JDK-8014510 (also on review) I'm starting to feel confident enough to make sjavac default for building jdk9.
