I use a servlet called "serve' in order to serve files from GCS using the blobstoreService.
I've never had problems before but since upgrading to the latest SDK with Jetty 9 and Java 8 runtime, I get an error when file names (as part of the url) contain a colon (':') character.
This problem doesn't occur on GAE's servers.
As a workaround I've renamed the files on my development server so that they don't contain that character. But it's only a temporary fix.

Stack trace for a request to the url: "/serve/project/6443687894581248/myfile:1234"
pointing to a file name "myfile:1234".

Mind, the request doesn't get redirected to the "serve" servlet. Instead DevAppServerModulesFilter sends it to StaticFileFilter,

java.nio.file.InvalidPathException: Illegal char <:> at index 76: C:\workspace\Iridium\src\main\webapp\/serve/project/6443687894581248/myfile:1234.js/index.html
