Returns a resource bundle using the specified base name, target locale, class loader and control. Unlike the getBundle, the given control specifies how to locate and instantiate resource bundles. Conceptually, the bundle loading process with the given control is performed in the following steps.

This factory method looks up the resource bundle in the cache for the specified baseName, targetLocale and loader. If the requested resource bundle instance is found in the cache and the time-to-live periods of the instance and all of its parent instances have not expired, the instance is returned to the caller. Otherwise, this factory method proceeds with the loading process below.
The ResourceBundle.Control.getFormats(String) method is called to get resource bundle formats to produce bundle or resource names. The strings "java.class" and "java.properties" designate class-based and property-based resource bundles, respectively. Other strings starting with "java." are reserved for future extensions and must not be used for application-defined formats. Other strings designate application-defined formats.
The control.getCandidateLocales method is called with the target locale to get a list of candidate Locales for which resource bundles are searched.

The control.newBundle method is called to instantiate a ResourceBundle for the base bundle name, a candidate locale, and a format. (Refer to the note on the cache lookup below.) This step is iterated over all combinations of the candidate locales and formats until the newBundle method returns a ResourceBundle instance or the iteration has used up all the combinations. For example, if the candidate locales are Locale("de", "DE"), Locale("de") and Locale("") and the formats are "java.class" and "java.properties", then the following is the sequence of locale-format combinations to be used to call control.newBundle.

Locale	format
Locale("de", "DE")	java.class
Locale("de", "DE")	java.properties
Locale("de")	java.class
Locale("de")	java.properties
Locale("")	java.class
Locale("")	java.properties

If the previous step has found no resource bundle, proceed to Step 6. If a bundle has been found that is a base bundle (a bundle for Locale("")), and the candidate locale list only contained Locale(""), return the bundle to the caller. If a bundle has been found that is a base bundle, but the candidate locale list contained locales other than Locale(""), put the bundle on hold and proceed to Step 6. If a bundle has been found that is not a base bundle, proceed to Step 7.
The control.getFallbackLocale method is called to get a fallback locale (alternative to the current target locale) to try further finding a resource bundle. If the method returns a non-null locale, it becomes the next target locale and the loading process starts over from Step 3. Otherwise, if a base bundle was found and put on hold in a previous Step 5, it is returned to the caller now. Otherwise, a MissingResourceException is thrown.
At this point, we have found a resource bundle that's not the base bundle. If this bundle set its parent during its instantiation, it is returned to the caller. Otherwise, its parent chain is instantiated based on the list of candidate locales from which it was found. Finally, the bundle is returned to the caller.

During the resource bundle loading process above, this factory method looks up the cache before calling the Control.newBundle(String, Locale, String, ClassLoader, boolean) method. If the time-to-live period of the resource bundle found in the cache has expired, the factory method calls the control.needsReload method to determine whether the resource bundle needs to be reloaded. If reloading is required, the factory method calls control.newBundle to reload the resource bundle. If control.newBundle returns null, the factory method puts a dummy resource bundle in the cache as a mark of nonexistent resource bundles in order to avoid lookup overhead for subsequent requests. Such dummy resource bundles are under the same expiration control as specified by control.

All resource bundles loaded are cached by default. Refer to Control.getTimeToLive(String,Locale) for details.

The following is an example of the bundle loading process with the default ResourceBundle.Control implementation.

Conditions:

Base bundle name: foo.bar.Messages
Requested Locale: Locale.ITALY
Default Locale: Locale.FRENCH
Available resource bundles: foo/bar/Messages_fr.properties and foo/bar/Messages.properties

First, getBundle tries loading a resource bundle in the following sequence.

class foo.bar.Messages_it_IT
file foo/bar/Messages_it_IT.properties
class foo.bar.Messages_it
file foo/bar/Messages_it.properties
class foo.bar.Messages
file foo/bar/Messages.properties

At this point, getBundle finds foo/bar/Messages.properties, which is put on hold because it's the base bundle. getBundle calls Control.getFallbackLocale(String, Locale) which returns Locale.FRENCH. Next, getBundle tries loading a bundle in the following sequence.

class foo.bar.Messages_fr
file foo/bar/Messages_fr.properties
class foo.bar.Messages
file foo/bar/Messages.properties

getBundle finds foo/bar/Messages_fr.properties and creates a ResourceBundle instance. Then, getBundle sets up its parent chain from the list of the candiate locales. Only foo/bar/Messages.properties is found in the list and getBundle creates a ResourceBundle instance that becomes the parent of the instance for foo/bar/Messages_fr.properties.

Parameters:

baseName     the base name of the resource bundle, a fully qualified class name

targetLocale     the locale for which a resource bundle is desired

loader     the class loader from which to load the resource bundle

control     the control which gives information for the resource bundle loading process

Returns: a resource bundle for the given base name and locale

Exceptions:

NullPointerException     if baseName, targetLocale, loader, or control is null

MissingResourceException     if no resource bundle for the specified base name can be found

IllegalArgumentException     if the given control doesn't perform properly (e.g., control.getCandidateLocales returns null.) Note that validation of control is performed as needed.

Since: 1.6

`baseName`		the base name of the resource bundle, a fully qualified class name
`targetLocale`		the locale for which a resource bundle is desired
`loader`		the class loader from which to load the resource bundle
`control`		the control which gives information for the resource bundle loading process

`NullPointerException`		if `baseName`, `targetLocale`, `loader`, or `control` is `null`
`MissingResourceException`		if no resource bundle for the specified base name can be found
`IllegalArgumentException`		if the given `control` doesn't perform properly (e.g., `control.getCandidateLocales` returns null.) Note that validation of `control` is performed as needed.
