I can't submit a real patch since it would have major impacts on code
base (InternationalizationManager is already used by several classes)
and would require more discussion before.

Anyway, here is my current quick-and-dirty (cache or proper
synchronizations are missing) version of InternationalizationManager
keeping maximal compatibility with trunk

package org.tellurium.i18n

import java.text.MessageFormat
import org.tellurium.config.Configurable

/**
 * InternationalizationManager - provides internationalization support

public class InternationalizationManager implements Configurable
{
  private Locale locale;
  private Set<String> bundleBasenames;
  private Map<Locale, Set<ResourceBundle>> bundles;

  public InternationalizationManager()
  {
    bundleBasenames = new HashSet<String>();
    bundleBasenames.add("DefaultMessagesBundle");

    bundles = new HashMap<Locale, Set<ResourceBundle>>();
    locale = Locale.getDefault();
  }

  public void setResourceBundles(String ... bundleNames)
  {
    for (String bundleName: bundleNames)
    {
      addResourceBundle(bundleName);
    }
  }

  public void addResourceBundle(String bundleName)
  {
    bundleBasenames.add(bundleName);
  }

  protected void checkResourceBundlesLoaded(Locale locale)
  {
    Set<ResourceBundle> bundleSet = bundles.get(locale);
    if (bundleSet == null)
    {
      bundleSet = new HashSet<ResourceBundle>();
      bundles.put(locale, bundleSet);

      for (String bundleBasename: bundleBasenames)
      {
        bundleSet.add(ResourceBundle.getBundle(bundleBasename,
locale));
      }
    }
  }

  public String translate(String messageKey, Object ... arguments)
  {
    checkResourceBundlesLoaded(locale);

    String result = null;
    Set<ResourceBundle> bundleSet = bundles.get(locale);
    for (ResourceBundle bundle: bundleSet)
    {
      try
      {
        result = bundle.getString(messageKey)
      }
      catch (MissingResourceException)
      {
        // ignored
      }

      if (result != null)
      {
        break;
      }
    }

    if (result == null)
    {
      throw new MissingResourceException("Can't find resource",
getClass().getName(), messageKey);
    }

    return MessageFormat.format(result, arguments);
  }

  public void setLocale(Locale locale)
  {
    this.locale = locale
  }

  public Locale getLocale()
  {
    return locale
  }

  // Kept for compatibility
  public void createDefaultResourceBundle(Locale locale)
  {
    // Already done
  }
}
