resourceBundle = Platform.getResourceBundle(bundle); returns null

Question

hello,

I am developing an Eclipse Plugin.

I am using the following call to get ResourceBundle:

bundle = Platform.getBundle(PLUGIN_ID);

resourceBundle = Platform.getResourceBundle(bundle);

bundle returns correct value, but resourceBundle always returns null. There was no exception happening when this is called,

My plugin_en.properties file is located parallel to the src folder.

I saw other sample plugin did the same thing but I did not understand why resourceBundle returns null.

Thanks for your help.
