Jersey 2.2 Client POST request to Parse.com utf-8 issue - parse-platform

Question

I am a begginer in Dropwizard / Jersey so please bear with me. I am creating request from my Dropwizard application resource:
Client client = new JerseyClientBuilder(environment)
.using(new JerseyClientConfiguration())
.build("my-app-name");
String response = client
.target("https://api.parse.com/1/functions/myFunction")
.request(MediaType.APPLICATION_JSON)
.accept(MediaType.APPLICATION_JSON)
.header("X-Parse-Client-Key", "mysecredclientcode")
.header("X-Parse-Session-Token", "mysecretsessiontoken")
.header("X-Parse-Application-Id", "mysecretapplicationid")
.post(Entity.text(
"{\"postId\":\"xP0Jc2lrqS\"}"
));
I think I tried all possible variations of Entity.* followed by MediaType.* with no luck.
This should work according to documentation. And I can call other endpoints of my app locally this way with no problems. But requests to parse.com return following entity:
{"code":107,"error":"invalid utf-8 string was provided"}
When I curl from bash I get expected response. I feel like I tried everything, can you please point me in the right direction, what am I doing wrong here?
curl request that works:
#!/usr/bin/env bash
curl -X POST \
-H "X-Parse-Application-Id: mysecretapplicationid" \
-H "X-Parse-Client-Key: mysecretclientkey" \
-H "X-Parse-Session-Token: mysecretsessiontoken" \
-d '{"postId":"xP0Jc2lrqS"}' \

Just in case you still facing this issue, I solved this adding in my maven project these properties:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
</properties>
