> The spec says:
> "...
> First, it attempts to load a class using the candidate bundle name. If such a class can
be found and loaded using the specified class loader, is assignment compatible with ResourceBundle,
is accessible from ResourceBundle, and can be instantiated, getBundle creates a new instance
of this class and uses it as the result resource bundle."
> The following is corresponding code fragment from ResourceBundle:
> ...
>         try {
>             Class<?> bundleClass = Class.forName(bundleName, true, loader);
>             bundle = (ResourceBundle) bundleClass.newInstance();
>             bundle.setLocale(locale);
>         } catch (LinkageError e) {
>         } catch (Exception e) {
>         }
> ...
> As we can see "bundle" class instance may be created even if specified instantiation
conditions are not satisfied.
> The bug causes 'Struts test' (http://issues.apache.org/jira/browse/HARMONY-3597) failure.
> Attached archive contains simplified test which reproduces struts test situation. Just
unzip and execute:
>   javac *.java
>   java b
> RI test output:
> ------------------
> $ java b
> p: set class to 'b'
> java.util.MissingResourceException: Can't find resource for bundle java.util.PropertyResourceBundle,
key nonexistent
> java.util.MissingResourceException: Can't find bundle for base name a, locale en_US
> java.util.MissingResourceException: Can't find bundle for base name java.lang.Object,
locale en_US
> p: found string 'Name' using key 'name'
> PASSED
> DRLVM test output:
> -------------------------
> $ java b
> p: set class to 'b'
> p: set class to 'b'
> java.util.MissingResourceException
> p: set class to 'a'
> java.util.MissingResourceException
> java.util.MissingResourceException
