My MBP with MacOS 10.14.6 + java 1.8.0 shows the following error when starting. Any idea?

Thanks for the report!

It seems AboutHandler was not available in Java 8. The best solution is to update to Java 11.
Java 11 is most current LTS version, and seems to be available for most platforms, either from package management (linux) or from https://adoptopenjdk.net/ for Windows and Mac.
I see little reason to maintain java 8 compatibility, so I have updated Java requirement to Java 11 in web pages.
