Hi guys,
we had an RCP Product based on 4.1 using the compatibility layer. After switching the target platform to 4.2.2 the theming via css didn't work anymore on a deployed product, it only works in the IDE. Ater looking at the code in AbstractCSSEngine we found a change since 4.1


4.1:
URL url = FileLocator.resolve(new URL(trim.addTrailingSeparator().toString() + ((CSSImportRule) rule).getHref()));
InputStream stream = url.openStream();


4.2.2
URL url = FileLocator.resolve(new URL(trim.addTrailingSeparator().toString() + ((CSSImportRule) rule).getHref()));
File testFile = new File(url.getFile());
if (!testFile.exists()) {
  //look in platform default
  String path = getResourcesLocatorManager().resolve(((CSSImportRule) rule).getHref());
  testFile = new File(new URL(path).getFile());
  if (testFile.exists()) {
    url = new URL(path);
  }
}
InputStream stream = url.openStream();


This won't work if the file is in a deployed bundle.
We are using the "org.eclipse.e4.ui.css.swt.theme" extension point in our product

<extension
        point="org.eclipse.e4.ui.css.swt.theme">
     <theme
           basestylesheeturi="css/e4_day.css"
           id="default"
           label="%Theme_Default">
     </theme>
     <theme
           basestylesheeturi="css/e4_dark.css"
           id="dark"
           label="%Theme_dark">
     </theme>
  </extension>


Is this a known bug?
