Codename One CSS box shadow compiling error (on Arch Linux)

I am finalizing an Android application on Arch Linux that I started on Ubuntu. The IDE is Eclipse.

When I run the code on Arch, I get a MissingNativeBrowserException.

Narrowing the problem down, I found that the responsible line of code is related to the box-shadow in the theme.css file:

box-shadow: inset 0px 0px 2pt 1pt rgba(255, 255, 255, 0.7);

Due to prior issues, I am using Java ZuluFx, instead of CEF, but I don't know if this related to the issue.

Below is the full stack-trace :

Our CEF support doesn't seem to work on Arch Linux at this time. See this: https://github.com/codenameone/CodenameOne/issues/3374

That's a problem since the CEF support is integral to newer functionality in Codename One and is now a part of the designer tool as well. I'm not sure when/if we'll be able to address this since I'm not sure I know where to begin.

If you wish to continue using the workaround of removing CEF there will be a couple of problems:

  • You will need to do it every week as we push out CEF updates
  • You will need to use an older version of the designer that doesn't try to use CEF either

For your convenience I placed an old version of designer (pre-cef change) here: https://www.codenameone.com/files/updates/old/designer_1.jar
