Description
Environment (Required on creation):
- Camunda Jenkinkins 7.16 Release CI
- JDK 11
Description:
The 7.16[-TEST]-RELEASE-build-camunda-bpm-CE-tags job builds the JavaDocs of the project using the maven-javadoc-plugin. The plugin is on version 2.9.1. When running the maven-javadoc-plugin on JDK 11, a bug is triggered (https://issues.apache.org/jira/browse/MJAVADOC-540) and the build fails.

Observed Behavior (Required on creation):
The 7.16 release can't complete.
Expected behavior (Required on creation):
The 7.16 release completes successfully.
Root Cause (Required on prioritization):
A bug in the maven-javadoc-plugin 2.9.1 when run on JDK 11.
Solution Ideas (Optional):
The related ticket in the maven-javadoc-plugin https://issues.apache.org/jira/browse/MJAVADOC-540 suggests bumping the plugin version to 3.0.1 where a fix is present.
