Steps to Reproduce

• perform a GET request using HTTP2Adapter on a HTTP 1/1 only backend
• repeat previous step many times (how many can vary: maybe 5, maybe 10) and maybe quickly - not sure exactly for the details
• trace the HTTP requests

Expected Result

all requests must have the Content-Length HTTP header (required on HTTP 1/1, optional only on HTTP 2/0)

Actual Result

Most of the requests do have the Content-Length header but some others don't
