JWT module Javadoc split package issue on JDK16+

https://lists.apache.org/thread/g85x7c1f1lkcjrw37rdq0zd6mokr8lsx

On Solr main using JDK 17, I am getting the following when running
`./gradlew check -x test`. I've been getting this for a few weeks but
finally digging into why.

It looks like this could be because of split packages? jwt-auth and core
both having org.apache.solr.handler.admin.api? I don't know how to debug
this further yet.

I'm specifically using this version of JDK 17 on an M1 Mac:

openjdk version "17.0.3" 2022-04-19
OpenJDK Runtime Environment Temurin-17.0.3+7 (build 17.0.3+7)
OpenJDK 64-Bit Server VM Temurin-17.0.3+7 (build 17.0.3+7, mixed mode)

It looks like this same error is happening on Jenkins for a wide variety of
JDKs: searching for "All tests passed"

JDK 16.0.2
JDK 17.0.3
JDK 18
JDK 19-ea+27

However it looks like this might only be happening on main? I only see
these failures on main for the past ~30 days. These also look to only
happen on Policeman jenkins - but I would guess this is due to the JDK
version being updated there compared to Apache ASF servers?
