Hi Alan, Dmitry,
thanks a lot for your help. Alan's suggestion to move the dependency
from src/jdk.jcmd/share/classes/module-info.java to
src/jdk.jcmd/$OS/classes/module-info.java.extra works fine. After
doing that change I could successfully build on AIX. I'll open a bug
for this and post a webrev later today. As I'm not a jigsaw committer
I'll probably need a sponsor though :)
Regards,
Volker
