JBoss AS7 app deployed on a Mac can't find com.apple.laf.AquaLookAndFeel

Question

We're migrating to JBoss AS7 from an older version of JBoss and we use JFreeChart in one part of our app:

chart = ChartFactory.createStackedBarChart( "", "", "Data", dataset,
            PlotOrientation.HORIZONTAL, true, false, false );

When we hit this line, we get the stack trace below indicating that com.apple.laf.AquaLookAndFeel can't be found. We only see this issue on a Mac which makes sense given the com.apple.laf package name. Running on a Linux server seems to work fine. Is there something we need to do to get AS7 on a Mac to recognize Apple's look and feel classes?

All of the Macs I've tried this on are fully updated as of 4/26/12. I haven't been able to find one that has some of the older JVMs.

Stack trace:

For now we've been able to get around this problem by specifying the default look and feel as a system property when starting JBoss:

-Dswing.defaultlaf=javax.swing.plaf.metal.MetalLookAndFeel

This seems like more of a hack so if there's a better way, we'd like to try that.

I'm not really sure how to test where exactly to add this, but you need to add com.apple.laf,com.apple.laf.resources as dependencies. In the CLI GUI that ships with AS 7 it's defined in the JAVA_OPTS with -Djboss.modules.system.pkgs=com.apple.laf,com.apple.laf.resources. You could add that to your standalone.conf or domain.conf depending on which mode you're running in.

You might also just try adding Dependencies: com.apple.laf,com.apple.laf.resources to your MANIFEST.MF in your deployment too. I'm not sure if that will work, but it's probably worth a test.

Not sure if related, but for me adding fork="true to the <java ...> task in the Ant file helped.
