Double response content in java17

[dcremo]

I'm using spring-httpserver-timings-java17 version 0.0.1 in SpringBoot v3.1.4 and Java jdk 17.0.3.1, and I'm getting a doubled text in the response, for example (omitting full token) on a RestController GET request

{
"token": "eyJhbGciOiJI...."
}{
"token": "eyJhbGciOiJI...."
}

Not sure if it is a bug or misconfiguration.
Thanks
