Моя сборка муравья неожиданно начала выдавать javax.naming.NoInitialContextException: необходимо указать имя класса в среде или системном свойстве

У меня есть файл build.xml, который отлично работал до вчерашнего дня, сегодня он внезапно уставился на исключение... Я не делал никаких изменений в приложении, он успешно идентифицировал имя JNDI ранее, я не могу понять, что вызвало его не удается.

javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
