Plugin Crashes in IntelliJ "Cannot fetch remote documentation: internal error"

[SHenckel]

This happens when I install the plugin and enable it for the project, then open javadoc quickviewer in the project.

This is the logfile entry:

Same issue with 2020.2.1

Must be the problem that IntelliJ does not have tools.jar in the classpath, but after that still is not working with no further information from IntelliJ.
