Migrate to Java 11
I read a bit about current Java development, so I open this issue for discussion:
Java 11 (released in Sept. 2018) is the next long-term-support version after Java 8. So I guess at some point we should consider migrating. Normally, this should be easy - however, we have seen issues (compile errors) with Java versions > 8. Not sure how serious they are, i.e. how easy to fix.
There has been a lot of development after Java 8 (apparently the module system, introduced in Java 9, had a larger impact, https://en.wikipedia.org/wiki/Java_Platform_Module_System).
- The end of live of Java 8 is January 2019 (this month) - after this there are no public updates anymore.
- For advantages listed at "Why upgrade from JDK 8 to JDK 11?" (security and increased speed and better garbage collection)

There are many sources on the internet about the migrating step:
