Hi Team,
We are seeing two types of threads created from Jetty http2 library i.e qtp and HttpClient@ threads in thread dump, We want to know for one http2 Client connection how many qtp and HttpClient@ thread will be created. And When will these threads get terminated? When we create multiple Http2 Client connections to send requests to endpoint, we are observing that qtp and
HttpClient@ thread count increasing drastically.
