=== Why can't I load properties using UIDefaults?

You may encounter this problem while porting a Swing application to the NetBeans platform or when using a third-party library like SwingX.  While the following code works in a standalone Swing application, it does not load the property in a platform-based application:

[source,java]
----

UIManager.getDefaults().addResourceBundle("com.example.foo.sample");
myLabel.setText(UIManager.getString("greeting"));
----

This fails in the platform because of link:http://bugs.sun.com/view_bug.do?bug_id=4834404[JDK bug #4834404].
Although the best solution is to replace the original code to load properties in a way that uses the correct class loader,
that may not be possible when using a third-party library.
In these cases, your module can work around the problem by using code similar to this:

[source,java]
----

UIDefaults def = UIManager.getDefaults();
ResourceBundle bundle = ResourceBundle.getBundle("com.example.foo.sample");
Enumeration<String> e = bundle.getKeys();
while (e.hasMoreElements()) {
   String key = e.nextElement();
   def.put(key, bundle.getString(key));
}
----

Yet another alternative is to ensure the resource bundles are available to the startup classloader.
You can do this by placing the JAR containing the resource bundles
in the `lib` subdirectory of your `platform` cluster,
although this workaround has not been tested.

Note: An (untested) possible workaround is to first call UIManager.put ("ClassLoader", Lookup.getDefault().lookup(ClassLoader.class)).
