Hi Enrico,
On a cursory glance of the maven compiler plugin release notes and the
recent JDK 16 changes, I don't see anything obvious stand out that would
fit the observed change.
So as Rory suggested, please file an issue and let us know what the ID is.
cheers,

Rory,
it looks like ZookKeeper does not build on JDK16 (it does with JDK15)
my error is:

from javac help it looks like "-Xdoclint:-missing" is a valid option
in order to reproduce the failure just clone zookeeper from github
git clone https://github.com/apache/zookeeper

JAVA_HOME=/path/to/jdk-16 mvn clean package -DskipTests
Any hint ?
