    Description

      AbstractRestAdapterClient.java
      /**
 * Initializes the REST adapter.
 */
public AbstractRestAdapterClient() {
   ResteasyProviderFactory instance = ResteasyProviderFactory.getInstance();
        List<MessageBodyReader<?>> messageBodyReaders = getMessageBodyReaders();
        for (MessageBodyReader<?> reader : messageBodyReaders) {
            instance.addMessageBodyReader(reader);
        }
        RegisterBuiltin.register(instance);

      If quite a lot rest clients are created in parallel we disocver the following exception sometimes. It's not deterministic.

          Bug - A problem that impairs or prevents the functions of the product. RESTEASY-1044 ConcurrentModificationException on InterceptorRegistry

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
