stream caching not configurable for rest consumer?

[Vojtech Fried]

Hi,

I am trying to fix upload of huge files via camel rest endpoint. The problem is 
that stream caching enables itself in this case (without being enabled in camel 
context or the route), but when camel asks a StreamCachingStrategy if the data 
should be moved from memory to file, it always says no, because it has 
"enabled" flag false (because no one enabled stream caching).

There is a Jira issue https://issues.apache.org/jira/browse/CAMEL-8821 that 
should have fixed it, but it actually did not, because as the last comment 
says, it calls a wrong method "readResponse..." instead of "readRequest...", 
the fix is only in "readRequest..." method. So I think it should be reopened.

Is there any other way how to disable stream caching?

My code is in configure method in a class that extends RouteBuilder:

restConfiguration()
            .contextPath(...)
            .enableCORS(true)
            .component("servlet")
rest("...")
            .id("...")
            .produces("application/json")
            .post("...")
            .to("direct:...");
