*
* The only really important piece of code is the
* {@link org.apache.http.conn.ManagedClientConnection#releaseConnection()} implementation,
* where the connectionCounter is decremented when a managed connection instance
* is released by AHC runtime. In our test, this is expected to happen
* as soon as the exception is created for an error response
* (as the error response entity gets buffered in
* {@link org.glassfish.jersey.client.JerseyInvocation#convertToException(javax.ws.rs.core.Response)}).
