Ao tentar carregar uma configuração a partir de uma classe anotada com @configuration, em um cenário de concorrência, ocorre o erro abaixo.

É possível observar pelo trace que existem 3 threads tentando carregar a configuração simultaneamente.

@clovisjunior , basicamente é um serviço REST que injeta uma classe CMSConfig, que está anotada com @configuration(type = ConfigType.SYSTEM).

Quando este serviço é chamado de forma concorrente ocorre o erro. No caso, ocorre no carregamento de uma página de uma aplicação angular 2, que faz 3 chamadas assíncronas para serviços desta classe que injeta CMSConfig, gerando a situação de concorrência.
