Is this flaky? It should run properly always.

This test always passes when it alone is executed. When running in batch with other tests, the receiver is getting some unwanted spans and assertions being failed. I tried excluding them in TEST_WRITER.waitForSpans(count, exclude_predicate), but couldn't make it work with batch

Description
In OkHTTP Tracing interceptor, while capturing response body it is trying to attempt
response().body().string(), the behaviour of string() function for non-BOM response is, if the response has a Content-Type header that specifies a charset, that is used else defaults to utf-8. For cases when original response is encoded ingzipthis causes response parsing failure as the response that interceptor returns is one with modified type/charset and results in below error in application.ref: https://square.github.io/okhttp/3.x/okhttp/okhttp3/ResponseBody.html
Other issue, is that in case of gzip encoded response, we need to decompress it read response in order to set as span attribute correctly.
Testing
Verified with response being of type gzip encoded and application/json.
Verified for non-utf8 parsing
