Description

Initially reported in FELIX-1957:

The latest changes to the webconsole makes it again incompatible with the OSGi/Minimum EE:

• UUID used in ConfigurationRender is missing in OSGi/Minimum-1.2
• Collections.list(Enumeration) used in ComponentsServlet & ComponentConfigurationPrinter is not support by OSGi/Minimum-1.1. Although it is added in OSGi/Minimum-1.2, it's better for wider compatibility to replace this method with own. Simple implementation is given below:
  class WebConsoleUtil {
  ....
  /**

• This method is the same as Collections#list(Enumeration). The reason to duplicate it here,
• is that it is missing in OSGi/Minimum execution environment.
• @param e the enumeration which to convert
• @return the list containing all enumeration entries.
  */
  public static final ArrayList list( Enumeration e ) { ArrayList l = new ArrayList(); while ( e.hasMoreElements() ) l.add( e.nextElement() ); return l; }

}

• Locale.Locale( String ) constructor is not available in OSGi/Minimum-1.1 (though available in OSGi/Minimum-1.2). However, for better compatibility we should use another approach.
  So instead of:
  DEFAULT_LOCALE = new Locale( "" )

it can be
DEFAULT_LOCALE = Locale.getDefault();

or even better (since our default language translation is English):
DEFAULT_LOCALE = Locale().ENGLISH
