Javascript not LOADED ON PAGE!


strange things happen nowadays. On my local jira server 8.2.5 javascript of web resource loads just fine.
When I deploy my plugin to DEV instance, nothing is loaded (no javascript file).
Can someone advice me what to do? We want to deploy our new plugin to PROD but are limited by this issue…

My webresource def:

<web-resource key="configuration-scheme-resources" name="Configuration scheme Handle Web resources">
    <resource type="download" name="configuration-scheme.js" location="/js/configuration-scheme.js"/>

Loading the resource:

    <title>Handle configuration scheme</title>
    <meta name="decorator" content="atl.admin">

Need to point out I googled and tried to remove first slash js/… and couple of other things, but nothing helped…
