Could not find group:com.sun.xml.bind, module:jaxb-core, version:2.1.16.
After digging into mavenrepository.com, there wasn't a jaxb-core 2.1.16 available.
I first thought the usual Sun / Oracle "download our RI zip to get the artifacts" game.Downloaded jaxb-ri-2_1_16.zip from https://jaxb.java.net/downloads/ri/ and unpacked it.
No jaxb-core.jar in the zip...
Then I found bug report https://java.net/jira/browse/JAXB-984
They messed up all the newer Jaxb 2.1.x version pom files. Bug seems to be partially resolved, only, as they closed it without fixing 2.1.16 (and some other versions).
Thats a "reference implementation" I like a lot...
