bad runtime process port ['']

[Joe Pardi]

When I switched my servlet app to use Spring MVC and Thymeleaf, it started reporting the error below.  Anyone have any ideas?

ERROR    2016-10-21 21:21:36,223 http_runtime.py:396] bad runtime process port ['']

WARNING: Null value for containerConfigProperties.get(devappserver.portMappingProvider)

I'll guess that since you're running the development server with a Java app, it's a standard environment app and you're launching it with 'mvn appengine:run'.

This error can happen if you have some Java 8 classes included in your project (as reported here), as the standard runtime still only supports Java 7. If this doesn't help and you can provide a reproducible sample project, I'd advise filing an issue on the google-cloud-sdk issue tracker.
