So the problem, as Oleg Nenashev noted, is a serialization failure for java.util.LinkedHashMap$Entry. You can reproduce this minimally as follows:

 
                                                                def remote_watch_urls = [
    './branches': 'my url/branches', 
    './releases': 'my url/releases'
    ]
for (foo in remote_watch_urls) {
  sleep 1
  echo "foo is ${foo}"
}
 
                                                            

The sleep will trigger Pipeline serialization and things blow up there. I'm not sure if we'll ever be able to actually fix that particular syntax, but there's a trivial workaround:

 
                                                                remote_watch_urls.each { foo ->
  sleep 1
  echo "foo is ${foo}"
}

...should work with no errors.
