No arrows at SpinnerItem for unstacked version = setWriteStackedIcons( false)

[dorin.ionescu]

The requested URL /sc/skins/Enterprise/images/DynamicForm/unstacked_spinner_sprite~2.png
was not found on this server.

(evaluation Enterprise version of 11 march 2016 )
The icons at stacked version are OK
The spinner is working even if you can not see the icons
The file without the "~2" can be found by server
the file with "~2" at the end is in the source war file (copied by me or software but is not uploaded or accessible at Google App Engine)
Is this a problem of this special character "~" tilde ?

See image attached

We haven't seen this before and we're not seeing other users complaining about inability to load files that have a ~ in the name from GAE. Are you having any trouble with non-GAE environments, or with your GAE environment when accessed from other machines or browsers? Because this problem might have to do with a browser extension or something on your client machine, rather than being a problem with GAE?

Same error on tablets - The Chrome browser is installed fresh without any extension

What about non-GAE environments? Is the problem just that GAE is refusing to deploy a file with a ~2 extension?
