Rest api and special characters in engine name

Hi

This https://github.com/camunda/camunda-bpm-spring-boot-starter/issues/104

made me wonder: are special characters allowed in a process-engine name?

In the issue, the webapp fails when the engine name is “sample-engine” but works when it is “sample”.

Thanks
Jan

See my reply in the issue. It is a bug inside the webapps. https://app.camunda.com/jira/browse/CAM-3500

Thanks. nasty issue, though … is it just hyphens? can I use colons and underscores?
