New release requires Java 11 or greater.

I could not get docx4j to pass tests with Java 8 and gave up for now.

Updated the project to Java 11 and released 0.64.0

If this is a show stopper for anyone please let me know and I will see if I can figure out how to keep Java 8 going a bit longer.

I usually try to stay on older language levels for a while. In my project I just transitioned to Java 9 to use module features but I have stayed away from Java 11 features. I could isolate the Java 11 requirement to the module that uses flexmark, but I would then have a Java 11 dependency for just one module at runtime. Do what you have to do but I think it could break a lot of people, particularly crossing the Java 8/9 boundary.

Hey! First off, thank you for the excellent library!
I maintain a wrapper in the Clojure language, which strives to maintain backwards compat as much as possible. As such, I would much prefer if we'd stay on Java 8 for as long as we can. I don't know how many of my users are on Java 8, but it aligns with the strong "updates shouldn't break anything" ethos.

Wouldn't it make sense to:

• keep the 0.x.x releases compatible with Java 8, and
• have a new 1.x.x release line that requires Java 11.

That would be compatible with the Semantic Versioning approach, which is more or less a de facto standard nowadays.

I used the latest version, but unfortunately it only supports jdk11, so I returned 6.2.2.
