When https://github.com/openjdk/jdk/pull/21431 is integrated, there will be a
new preview language feature: `requires transitive java.base;`. It would be
good to show a warning box in the javadoc about the use of the feature. This PR
is attempting to add such a warning box.
Given it is likely this feature will either graduate or be dropped in the span
of a few releases, I tried to make the code (relatively) easy to remove: it
should be enough to delete the `if (javaBase != null &&
indirectPackages.keySet().contains(javaBase)) {` and the then section, keeping
the else section + some slight cleanup.
The new javadoc can be seen here:
