Atlassian Confluence SDK Problem starting App 404

when starting a Confluence plugin I always get the following error:

I have tried several plugins and in Windows, Mac and Ubuntu. Unfortunately I always get this error when starting the current and also an older SDK. I have tried Oracle and OpenJdk, both version 8.The result is a 404 page when calling http://127.0.0.1:1990/confluence

The Tomcat log does not contain any errors...

Do you have the same problem, or do you know a solution?
