Thanks Thierry, this is very very helpful, I appreciate you looking into this.
First: I suggest we make MediaType.ALL the default in 2.1 and 2.2.
Second: I’ve made this change in my application, and it seemed to work
at first — but it turns out that the behavior of my resource, when I
don’t send an Accept header, has become unpredictable.
I have these two methods in my resource class:
@Get("html|xhtml")
public Representation getHtml(Variant variant)
and:
@Get("json")
public Representation getJson()
now that I’ve made this change, most of the time when I run my app and
make a request for this resource without the Accept header, I get back
a response with the Content-Type being text/html, which is what I want
and expect. However, sometimes when I start my app and make the
request, I get back a JSON response.
This is of course not acceptable; I need the behavior of my app to be
predictable and consistent. Unfortunately I can’t give you statistics
on how often this occurs; my app takes a long time to start up. Off
the top of my head, it seems to be around 20% of the time.
Can you suggest any theories for why this might be happening, and some
possible ways to prevent this from happening?
Thanks!
