Hi,

I'm currently looking at migrating a Jersey 1 application to Jersey 2.

One of the features we utilise is the ability in Jersey 1 to update the
ResourceConfig singletons collection at runtime. This gives us the ability
to add/remove Resource endpoints at runtime in a dynamic manner.

Basically, we instantiate Resources using OSGi then dynamically add or
remove the instance using config.getSingletons().remove(resource) and
config.getSingletons().add(resource); and then calling container.reload();

Jersey 2 has made this Collection un-modifiable now, and also the
ResourceConfig getSingletons() is now final so can't be overridden
(without violating the intent of the developer).

I'm try to use the HK Binder module to bind the instance (using
bind(object).to(blah.class) and passing the instance of the AbstractBinder
to config.registerInstances(), but I'm getting the following stacktrace
when I try to call the endpoint:

javax.servlet.ServletException: java.lang.IllegalStateException: Request
scope has been already shut down.
