There's only one possible issue on the 3.3 showcase. After loading the application for the first time after having been newly deployed, there's a ConcurrentModificationException exception. Everything works normally after reloading the page. This issue not always happens. It's still not clear if this is related to the JDK11.
There are a few other minor issues, but they don't seem related to the JDK11.
Note that the build script for the 3.3 samples had to be modified to compile with Java 1.6, instead of 1.5, as 1.5 seems to be unsupported by this JDK version.
