> RESTClientServlet uses URLEncoder.encode(..) on resource identifiers. This is ok most of the time, but breaks a client when there is a space in the association filter used used as part the identifier. Eg. Features and distributions use the name attribute in the association filter, so when one creates a feature with a space in the name "My Feature" the filter be something like (&(name=My Feature)). 
> The problem...
> URLEncoder.encode(...) encodes into application/x-www-form-urlencoded which is ok for a querystring, not for a URI.
> What happens...
> 1. URLEncoder.encode(..) will translated "My Feature" into "My+Feature" 
> 2. When a client (eg perl) uir_decodes this the result will still be "My+Feature"
> 3. Using this as identifier in for example an association will fail.
> My workaround...
