Subject Is HttpParameters Supposed to be Immutable
Date Tue, 21 Aug 2018 16:32:00 GMT
I was doing some work on a custom interceptor that was working with the HttpParameters class.
 At first glance, it appears that it is supposed to be immutable based on some of the exceptions
thrown for implementations of Map methods, for example:

    public Parameter put(String key, Parameter value) {
        throw new IllegalAccessError("HttpParameters are immutable, you cannot put value directly!");

    public Parameter remove(Object key) {
        throw new IllegalAccessError("HttpParameters are immutable, you cannot remove object

But then this method is there:

    public HttpParameters remove(Set<String> paramsToRemove) {
       for (String paramName : paramsToRemove) {
        return this;

Which is removing the parameter from the object, I would have expected that this return a
modified copy?

Just wondering the intentions of the class, and if this should be logged as a bug?
