The decision was: Qualified exports/opens to a non-observable module is 
NOT an error (see 
https://docs.oracle.com/javase/specs/jls/se11/html/jls-7.html#jls-7.7.2-310). 
javac will give an on-by-default lint warning instead.

The StackOverflow question says "Because I configured the compiler to 
treat warnings as errors (-Werror), the build fails." so the questioner 
should look at disabling the lint warning (see 
https://docs.oracle.com/en/java/javase/11/tools/javac.html#GUID-AEEC9F07-CB49-4E96-8BC7-BCC2C7F725C9).
