java.lang.NoClassDefFoundError: Could not initialize class net.sf.jasperreports.engine.util.JRStyledTextParser

Solution In Progress - Updated -

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 6.1.1

Issue

  • Our DR server throws NoClassDefFoundError but our Prod server, which has identical configuration with DR one, doesn't.

Resolution

  • Make sure that those servers have exactly the same configuration. We found that the problematic class, net.sf.jasperreports.engine.util.JRStyledTextParser, has a static initializer trying to load fonts. And if a related GUI library is not installed on the OS, it will fail to be initialized. Please confirm that your DR environment has a proper GUI library installed, which is likely found in the Prod environment. Or confirm that there is a system property, "-Djava.awt.headless=true", in your startup script.

Diagnostic Steps

From jasperreports-4.7.0-project.zip:

public class JRStyledTextParser implements ErrorHandler
{
    private static final Log log = LogFactory.getLog(JRStyledTextParser.class);

    private static final Set<String> AVAILABLE_FONT_FACE_NAMES = new HashSet<String>();
    static
    {
        //FIXMEFONT do some cache
        List<FontFamily> families = ExtensionsEnvironment.getExtensionsRegistry().getExtensions(FontFamily.class);
        for (Iterator<FontFamily> itf = families.iterator(); itf.hasNext();)
        {
            FontFamily family =itf.next();
            AVAILABLE_FONT_FACE_NAMES.add(family.getName());
        }

        AVAILABLE_FONT_FACE_NAMES.addAll(
            Arrays.asList(GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames())
            );
    }
        ...
