Create a test to run Eclipse SWTChart on the basis of the latest Eclipse IDE 2021-06 and the latest Java 16.

The latest Eclipse IDE and Java16 works fine. Some minor issues needs to be solved. Findings:

It seems this error occurred with the update to Java 8 previously https://bugs.eclipse.org/bugs/show_bug.cgi?id=530093 and had to be fixed in the Eclipse platform.

I vote against Java 16 as that will EOL in September. https://www.oracle.com/java/technologies/java-se-support-roadmap.html At least one release should be on the current LTS, then further upgrade steps can be undertaken.

I agree, we should first migrate to Java 11. If full Java 17 support is available next year, we could give the next LTS (Java 17) a try in 2022.

We use Tycho 2.7.0 now and Java 11. SWTChart works fine with GTK3 on Ubuntu 2021.10 with X11 and Wayland. For compatibility reasons with others projects, let's stay a while on Java 11.
