How to use an annotation processor which depends on java.xml.bind?

[Jonathan Gibbons]

You need to add java.xml.bind into the runtime environment underlying 
javac, instead of the compilation environment containing the classes 
being compiled.

If you are running javac from the command line, use -J-add-module to 
pass the option to the underlying JVM.

If you are running javac via an API in an existing JVM, that JVM has to 
be configured to include the desired module(s).
