Rostislav Svoboda commented on ISPN-9824:
-----------------------------------------

When playing with javadoc/doclets module I get 36 errors.

When I did following changes I got 2 errors saying the same - package com.sun.tools.doclets.formats.html does not exist.
This package was present in Java 9 but was not exported, in Java 10 or 11 it vanished completely.
This is probably due to http://openjdk.java.net/jeps/221

Having custom doclets seems like a big maintenance burden.

> It's not able to build Infinispan with JDK 11.
> Module infinispan-commons contains JDK specific classes which requires to be built in JDK 9+ (JDK 11 is LTS) but it's not able to build the whole Infinispan project with distribution profile related to fails on missing classes for infinispan-doclets module (referencing com.sun.javadoc*) using tools.jar which are not the part of JDK 9+ anymore. The failure is also on generating javadoc for infinispan-commons which uses sun.reflect.Reflection.getCallerClass which is discontinuing in JDK 11.
