Thanks! In the main time (just in case it may be of some use to someone), below is the workaroud I applied in order to find the primary Doclet class:
@Override public void init(final DocletEnvironment env, final jdk.javadoc.doclet.Doclet doclet) { StackWalker.getInstance(StackWalker.Option.RETAIN_CLASS_REFERENCE).walk(stream -> stream.filter(frame -> frame.getClassName().equals("mypackage.MyDoclet")) .map(frame -> frame.getDeclaringClass()).findFirst()).ifPresent(c -> init(c)); } /** * Invoked with the primary doclet class. * This is not MyDoclet.class because of different ClassLoader. */ protected void init(final Class<?> doclet) { // Invoke some method using reflection. } Martin Le 02/05/2018 à 20:23, Jonathan Gibbons a écrit : > FYI, the Taglet.init issue has been addressed. > > https://bugs.openjdk.java.net/browse/JDK-8201817 > > The issue about programmatic registration (addCustomTag) is still > under investigation. > > -- Jon >
