I've discovered what I believe is a bug in the new v1.3 Jar indexing feature.
If a Java resource bundle is accessed via ResourceBundle.getBundle() in an
indexed Jar a java.util.MissingResourceException is thrown if all of the
following are true:

  1. The only resource bundle file that is found for the selected locale is a
     default one. Meaning it has no explicit locale component (e.g.
     MyBundle.class or MyBundle.properties).
  2. The referenced resource bundle file is within a Java package.

Source:
package jarpkg;

import java.util.*;

public class JarIndexBug {
  private static final Class THIS_CLASS = JarIndexBug.class;

  private static final Locale LOCALE_DEFAULT = Locale.getDefault();
  private static final Locale LOCALE_SPANISH = new Locale( "es", "" );

  private static final String PROPERTY_BUNDLE_NAME = "jarpkg.MyPropertyBundle";

  private static final String[] STRING_IDS = {
    "yes.msg", "no.msg", "maybe.msg"
  };

  public static void main( String[] args ) {

    System.out.println( "\n" + THIS_CLASS.getName() + " Tests:" );

    doTest( PROPERTY_BUNDLE_NAME, LOCALE_DEFAULT );
    doTest( PROPERTY_BUNDLE_NAME, LOCALE_SPANISH );
  }

  private static void doTest( String bundleName, Locale locale ) {
    System.out.println( "\n Results: locale=" + locale.getDisplayName()
                      + ", bundleName=" + bundleName );

    ResourceBundle bundle = getBundle( bundleName, locale );

    if (bundle != null) {
      for (int i=0; i < STRING_IDS.length; i++) {
        String stringId = STRING_IDS[i];
        String string = bundle.getString( stringId );

        if (string == null) string = "**** STRING NOT FOUND ****";

        System.out.println( " " + stringId + "=\"" + string + "\"" );
      }
    }
  }

  private static ResourceBundle getBundle( String bundleName, Locale locale ) {
    ResourceBundle bundle = null;

    try {
      bundle = ResourceBundle.getBundle( bundleName, locale );
    }
    catch (MissingResourceException ex) {
      ex.printStackTrace();
    }

    return bundle;
  }
}


Resource Bundles:

jarpkg.MyPropertyBundle.properties:

yes.msg=yes
no.msg=no
maybe.msg=maybe

jarpkg.MyPropertyBundle_es.properties:

yes.msg=s?
no.msg=ning?n
