ADDITIONAL SYSTEM INFORMATION :
Window 10, android, gradle 7.4.2, JDK 11.

Used to work in JDK 8. Can't go back to 8 because the android gradle plugin we now need requires JDK 11.

A DESCRIPTION OF THE PROBLEM :
I have a multi-module project that gets published to Maven Central, and has, in the past always “worked” where “worked” was defined as, “we know we have undefined symbols in our javadoc, but what we have is sufficient for our community.” The javadoc tool would report missing symbols, but would still happily generate html.

Near as I can tell, somewhere around JDK 11, the JDK/Javadoc team decided that undefined symbols would be a hard fail. We were relying upon the “best effort” generation of HTML, which worked well for us for many years. With the change to the refusal to output any HTML when symbols are undefined our build is broken and we have 3rd party libraries for which symbols are undefined which we don't own and can not fix.



REGRESSION : Last worked in version 8


FREQUENCY : always
