Inject multiple @JsonPath parameters to bean method

[grzechol]

Hi guys,

I have a problem injecting multiple @JsonPath arguments using bean binding.

Here is my sample json:
{"key1":"val1","key2":"val2"}

My bean method processing that JSON:
@Handler
public void process(@JsonPath("$.key1") String value1, @JsonPath("$.key2")
String value2) {
    System.out.println("Got key1: " + value1);
    System.out.println("Got key2: " + value2);
}

And my route:
<route id="test">
    <from uri="timer://foo?period=0&amp;repeatCount=1" />
    <to uri="http4:localhost:8084/example_json" />
    <to uri="bean:myBean" />
</route>

I got the following exception message: "Property ['key2'] not found in path
$" (stacktrace: http://pastebin.com/TMrK4wC0)

Everything works perfectly fine when I use only one @JsonPath method
argument, key1 or key2 it doesn't matter. But it doesn't work with two
arguments, regardless of their order. I always receive error message taht
the second parameter is not found in path "$" regardless which one is second
- key1 or key2.

The weird thing is it works perfectly fine with JSON read from filesystem
instead of http service:

<route id="test">
    <from uri="file:/tmp/example?noop=true" />
    <to uri="bean:myBean" />
</route>

Log messages indicate Camel reads the same file twice to evaluate two
JsonPath expressions, but I'm not sure it it's true:

I'm using Apache Camel 2.17.1 with Jayway Json Path 2.0.0.
