Thomas Jodes updated CAMEL-21129:
---------------------------------
Description:
{{Rest Route creation fails with a NPE, setup using
restConfiguration().{color:#d8d8d8}clientRequestValidation{color}(true) with a
JSON-binding to a Java type like
rest("/foo").get("/bar").outType(MyType.class).to("bean:one?method=baz").}}
Root Cause: Changes from 4.6 to 4.7 in RestBindingAdvisorFactory#build(...)
local variable "outJson" is always null, leading to the NPE for sure at the
line seen in the exception trace below.
In 4.6, "outJson" [is created for sure here|#L76]]
In 4.7, "outJson" [remains null

and will [lead to the NPE here|#L174]].]
