Thanks a lot for holding that talk. I won't be able to attend by I can
make some suggestions.

You could maybe summarize the upcoming Java related changes in Buster. I
started thinking about a blog post on this topic, the freeze is the good
time to publish it. Some items worth mentioning:
- the transition to OpenJDK 11 and the massive effort involved (more
than 400 package updates the last time I counted)
- the state of the build tools. Ant and Maven are up to date, Gradle is
stuck at the last pre-Kotlin version. SBT still being worked on.
- the state of the JVM languages: Groovy 2.14, Scala 2.11.12 (2.12
requires SBT), Clojure 1.9. Kotlin is wanted but difficult to bootstrap.
- the state of the IDEs: Eclipse is gone (lack of maintainers), Netbeans 10
- on the application servers side: Jetty 9.4 and Tomcat 9, fully up to
date, and now with systemd integration.
- the reproducibility rate is now around 85% (Stretch was around 75%).

I have a script that compares the packages between two releases but I
haven't published it yet. I'll run it and post the result for the
stretch/testing differences (it doesn't addresses the maintainer/bug
counts though).
> What specific OpenJDK changes caused the most grief?
- New layout of the JDK installation
- Removal of tools.jar
- Removal of the JavaEE APIs (activation, JAXB, JAXWS...)
- Removal of javah
- javac source/target pre 1.6 removal.
- ByteBuffer return type changes (Java 11 compiled code breaks with 8)
- sun.misc.Unsafe breaking changes
- Javadoc pendantic errors, JQuery embedding
But let's not rant too much and keep the talk positive :)
